Brango Casino - Player claims that payment has been delayed.

I received an email actually like two or three indicating that I had been deposited 5500 to dollars only to find out after registering and giving out my information that the casino would deny that they had sent that now under fake circumstances the link to give out my personal info would have sent me to them right well this one does if it were fake I wouldn't have access to them thru that fake ad and they wouldn't have ended up with my Infirmayion so at this point I would like if possible for guru to enlighten me as to how to file a lawsuit thank you, and I do have the email they sent as proof

Dear Razo,

Thank you very much for submitting your complaint. We are sorry to hear about the issue with your withdrawal and understand your concern. However, please bear in mind that it’s quite usual for withdrawals to take a couple of days or even weeks to get fully processed. This means that it may take some time before your money appears in your account. This delay may be caused by unfinished KYC verification or a high volume of withdrawal requests.
That’s why we advise players to be patient, cooperate fully with casino, and wait at least 14 days after requesting their withdrawals before submitting a complaint.

If your account has been successfully verified, your game history checked, your withdrawal approved by the casino, and you still haven't received your winnings by 14 days since requesting the withdrawal, we will intervene and do our best to help you.
Thank you in advance for your patience and understanding.

Best regards,
Complaints Resolution Center

Dear Razo,

Have you received your withdrawal from the casino yet?

Hi no haven't received anything they mentioned something about 50 dlrs they wanted. Me to deposit but if you can get me a document outlining that the 50 dlrs will be reimbursed back with the 5500 I will borrow those 50 but I believe that was because the bal has to be 100 or above but just if you can get a resolution just have it legally binding and all I will do my best to fill in the cracks it's just I'm not gonna be running around so they can come up with another terrible thing that happened but if it's in writing signed by the authorized rep I will follow on it thank you
