The player from Greece made three withdrawal requests at Quick Win casino. The casino then requested identification documents, and after providing these, the player’s account was closed abruptly and without a specified reason. Despite several attempts to communicate, the casino states the decision is non-negotiable. We contacted the casino and found out that the player's account was blocked due to suspicioon that the 3rd party could've sponsor the player's deposits. We asked the casino, if they could check the player's proof of source of funds, therefore the player was requested to provide QuickSpin with the up-to-date tax return. The player followed the instuctions and finally confirmed receiving his withdrawals, so the complaint was closed as resolved.
