The problem always narrows down to one thing in such cases, not reading the T&C. Then they come up here, open a topic to make everyone aware how pathetic the named casino is and how they got scammed. Almost every casino that has a licence will enforce KYC to its user. After testing the casino and before making a big deposit it is advised to complete KYC. If you don't then you cannot withdraw. Contacting the support does help but that will take time.
Take for example, recently, the drivers license which is the document I used in verifying my account on binance expired, I believed I had no issue since I've already verified my binance account years back before the document expired, but that same week my drivers license expired, I was to deposit some Bitcoin to binance, but I discovered Ive been locked out completely, I can deposit nor withdraw, I was asked to submit my renewed drivers license, or go through another verification process with a new document that isnt expired ..
And since I was yet to apply for my drivers license to be renewed, I had to re-verify my account with my national id card before binance allowed me to deposit ..
They probably would have just allowed me deposit , and then refuse me from withdrawing, which is very bad if you ask me .
Because that shows that they never care about the security of the user account and that their concern about is the deposit they want to receive.
