Case summary

The player from Italy files a complaint regarding the closure of his Duospin.com account and the confiscation of approximately €1,500. While he accepts the account closure, he contests the confiscation, claiming the casino's reasons are vague and lack evidence. He requests concrete details and an impartial review of the situation.

Good evening,

I would like to file a complaint regarding the closure of my account on Duospin.com and the confiscation of my real balance of approximately €1,500.

I'd like to point out right away that I accept the closure of my account without hesitation, but I totally contest the confiscation of my real balance, which I believe to be unjustified.

The casino informed me that the closure was due to alleged violations of points 9.1 and 9.3 of the Terms and Conditions, but the reason given is extremely general and contains no concrete evidence or reference to specific plays, behaviors, or activities I allegedly engaged in.

Their response does not state:

– what "incorrect" strategy I would have used;

– which bets or gambling patterns would be considered "minimal risk";

– what technical logs would demonstrate system abuse;

– on what date or session the alleged infringement occurred.

I've asked the casino for more details and technical support, but so far I've only received standard, non-specific responses.

I therefore believe that the confiscation of the balance is not justified, as it is based on vague reasons and is not supported by evidence.

I kindly ask CasinoGuru to look into this matter and request the casino to:

concrete evidence of the alleged violations; detailed logs of the disputed games; the legal basis for the seizure of the real balance; an impartial review of the decision. I am available to provide screenshots, emails, and any information useful for evaluating the case.

Thanks for your assistance.

Hi Tommaso,


Thank you for your support and for filing a complaint.


I answer your questions:


*1. How long have I been a player and when was my account banned?*

I've been a customer of http://Duospin.com for a few months. My account was blocked a few weeks ago, without warning.


*2. How did I find out about the block*

I learned about this via an email from Duospin informing me that my account had been blocked and that it was being checked.


*3. What games did I play to build up my balance*

I have played both live casino games and sports betting.


*4. Did I reach my balance thanks to a bonus?*

No, I didn't reach my current balance through bonuses. My balance is the result of personal deposits and gambling winnings.


*5. Game Experience Description*

I use Duospin for personal entertainment. I play normally, without using prohibited strategies, without opening multiple accounts, and without using VPNs or other methods to circumvent the rules. Stakes vary depending on the game.


*6. Is the account verified?*

No, the account hasn't yet required KYC verification. The block occurred before I was asked to verify my documents.


I remain available to complete the KYC verification immediately and provide any documents necessary to unlock the account and funds.


Thank you and I look forward to hearing from you.


Best regards,

Dario *****

Hello Team Duospin,


Thanks for the update.


However, I am very disappointed with the way my audit is being handled.

First you write to me that you have not received the documents, even though I have already sent them more than 4 times and have screenshots.

Now you tell me that the verification failed, but without specifying the reason and after making me wait a long time.


So I ask you to be clear:

*What is the exact reason why my verification failed?

Which documents or information are incorrect?


I have sent everything several times and I am fully available to regularize immediately.

I won't accept further delays or generic responses. I need specific instructions to resolve and proceed.


I await a detailed and prompt response.

Dear Michal,


In reference to your last post, I totally dispute what you are attributing to me.


1. Suspicious behavior in sports betting: IT'S FALSE.

I've never exhibited any suspicious behavior. I've always bet regularly and within the terms. I don't understand the basis for your accusations.


2. Live matches played after a restriction: THIS IS FALSE.

I've never received any notification of restrictions on my sports betting account. How could I have violated a restriction I was never informed of? My account was always active and allowed me to play regularly.


I consider these accusations to be totally unfounded and damaging to me.


I don't accept being accused without evidence. I look forward to your detailed response, not a generic answer.

Dear Borrelida52,

Thank you for your response. However, I feel my previous message may not have been fully understood.

I have not accused you of anything. As I mentioned, I was informed by the casino team that a restriction was placed on your account regarding sports betting.

To move forward, I would appreciate your clarity on the following two points:

  1. Prior to playing the live games, had you only or mainly been placing sports bets?
  2. After the restriction was placed on your account — the one you claim you were unaware of — did you stop placing sports bets and place bets only in live games?

A simple yes or no to each question would be sufficient.

1. Before playing live games, did you bet only or mainly on sports?

Answer: NO. I bet on various games, not just sports.


2. After the restriction you claim you were unaware of was placed on your account, did you stop placing sports bets and start betting only on live sporting events?

Answer: NO. I never changed my betting habits. I wasn't aware of any restrictions and continued to play as the site always allowed.


My only priority is to get my money back and settle this matter amicably.

Dear Borrelida52,

Could you please clarify which games you played and the types and amounts of bets you placed? There appear to be significant differences between your account of events and the information provided by the casino.

You previously stated: "No, I've always played alone. I've never shared my account, I've never played with others, and I've never played while visiting."

You also stated: "NO. I never changed my betting habits. I wasn't aware of any restrictions and continued to play as the site always allowed."

However, the information and supporting evidence I have received from the casino appear to contradict these statements. I would therefore appreciate your clarification.

I have also requested further evidence from the casino, which should help establish the course of events once received.

Dear Michal, thanks for the update,


I'm happy to clarify the discrepancies the casino reports, because my only interest is getting my money back.


What games have I played, types and amounts:

I mainly played sports betting and I don't remember if I also played live baccarat.


On the alleged discrepancies:

I apologize if my previous answers seemed contradictory; that wasn't my intention. Let me explain:


1. When I said "I've always played alone," I meant that the account has always been used only by me; no one has ever had access to my credentials. I haven't shared the account.


2. When I said "I didn't change my betting habits," I meant that I didn't do it intentionally to circumvent a restriction, because I never received any email or notification informing me of a restriction. If the system allowed me to play, I assumed it was allowed. If I played more live games at a certain time, it was only because I preferred that game at the time, not because I was breaking any rules.


I never intended to violate the terms with opposite bets or anything else. If any play was interpreted as such, it was an inadvertent error due to inexperience, not a strategy.


I confirm that there are no other family or friend accounts linked to mine.


I remain available for any tests.


A thousand thanks,

Dear Borrelida52,

Thank you for your explanation. However, there are still inconsistencies between your responses that need to be clarified before I can fairly assess your complaint.

When I asked whether you had previously placed bets only or mainly on sports, you answered "NO" and stated that you played various games. In your latest response, however, you explicitly state that you mainly played sports betting.

You also previously stated that you never changed your betting habits. Your latest response instead explains why you might have played more live games at a particular time. My question concerned whether your betting activity actually changed, regardless of your reasons or whether you were aware of a restriction.

For clarity, by "live games", I mean live casino games, such as baccarat, live roulette, etc. rather than live sports betting. Please specify which casino games you played, approximately when you played them, and the usual amounts you wagered.

Regarding your statement that you always played alone, please also clarify whether you ever coordinated your bets with another person using a separate account. Confirming that nobody had access to your credentials does not answer this question.

Finally, you mentioned that any opposite betting could have been an inadvertent error. Are you referring to particular bets you remember placing? If you recall such bets, please describe them.

I am not drawing a final conclusion at this stage. However, an independent assessment requires accurate and consistent information from both parties. I would therefore appreciate direct answers to these outstanding points while I await the additional evidence requested from the casino.

Dear Michal,


Thank you for your patience, and I'll clarify this immediately to eliminate any inconsistencies. I apologize for the confusion.


1. Do you bet only or mainly on SPORTS?

I answered incorrectly before. Let me clarify: yes, I mainly bet on sports and then played a few games of live baccarat.


2. Have I changed my betting habits after a restriction?

No, my basic activity hasn't changed. I've always played both sports and live baccarat. If I've played more at the live casino over time, it was a normal gaming preference, not because I wanted to circumvent a restriction. I confirm that I wasn't aware of any restrictions.


3. Which LIVE CASINO GAMES have I played, when, and the stakes? I don't remember the stakes for live baccarat.


4. Have I ever coordinated bets with another person with a separate account?

NO. NEVER. I have never coordinated my bets with anyone, I have never made opposing bets with another person.


5. Inadvertent opposite bets I was referring to?

I'm not referring to any specific bet because I've never made opposite bets. I wrote "if" and it was interpreted as an error.


I confirm that my sole goal is to recover my funds.


Thank you for your time.

Dear Borrelida52,

Thank you for your clarification. I will assess your explanation against the casino’s evidence, and I have requested further records to establish the complete course of events.

The evidence supplied so far shows your account and another account placing closely matched bets on opposite baccarat outcomes on several occasions. The casino also states that this activity occurred during a single session after sports betting restrictions were imposed. This raises legitimate concerns that require careful examination, although I have not reached a final conclusion.

I acknowledge your denial of coordinating bets with another person. However, confirming that only you accessed your account and your claim that you have never coordinated your bets with anyone does not, by itself, rule out coordination between separate accounts, especially when the evidence provided indicates something else. Similarly, whether you knew about a sports betting restriction is separate from whether the subsequent baccarat activity involved prohibited conduct.

My assessment will focus on what the records substantiate and whether they justify the confiscation of your balance. I will update you once I have reviewed the additional evidence.
