Dear Katarina,
Thank you very much for your message and for assisting with my complaint.
Withdrawal request date: I requested my withdrawal on 15/09/2025 for the amount of €473.93.
Pending verification: Yes, according to VinciSpin, the only remaining step is to provide a "Source of Funds" document. However, I have already submitted authenticated bank statements (July–September 2025) showing both MB Way deposits and regular monthly Social Security income above €850.
Reason for not submitting additional documents:
The documents they now request (proof of deposit in PDF format) were already submitted and previously accepted by VinciSpin.
I even provided an official SIBS Backoffice digital confirmation, which is the highest level of transaction verification available in Portugal, containing the full transaction details (date, amount, merchant, and unique Log Key).
Moreover, I received an official reply from SIBS (the national payment processor operating MB Way) confirming that PDF proofs are not issued by them, and that any verification or proof of payment must be obtained through the issuing bank — which I already did by providing authenticated bank statements showing the MB Way deposits clearly and visibly.

These same statements were previously validated by VinciSpin, as I successfully completed a withdrawal in the past using the exact same documentation and payment method.
Bonus status: I have never accepted or used any bonuses, promotions, or free bets. My winnings of €473.93 were obtained solely from normal betting activity using my own deposited funds.
In summary, VinciSpin is withholding my verified winnings (€473.93) despite having already validated all required documents and despite me providing additional official evidence directly from SIBS and my bank.
Their repeated requests for "PDF proofs" or "Source of Funds" documents are unreasonable, redundant, and disproportionate to a total deposit of only €75 (€25 + €50).
Thank you very much for your help in resolving this matter.
Kind regards,
