I don't wish to dwell on this matter any longer, but I would appreciate hearing your thoughts. Personally, I feel that this is a highly questionable practice, allowing users to continue gambling while demanding verification for withdrawals, and then conveniently erasing the tickets and evidence. It appears to be nothing short of shady and potentially predatory to me.
Even crypto exchange where I trade, (all of them that ive used), still allow customers to trade, buy, sell, coins while the customer is suspended from withdrawing due to one issue or the other, this is something I have personally experienced myself on not just one or two exchanges but on as many of them I've used and had minor to serious withdrawal issues.
So I do not see this practice as evil in any way, you simply was the one who decided to keep gambling amid your withdrawal issues, and unfortunately lost all your winnings.. So trying to now turn back and blame the casino for the result of your own decisions is rather not fair..
When the Casino asked you to pass kyc verification before you can withdraw, if you know you aren't ready to lose any part of that money, you should have abstained from gambling at that time and pursue the kyc verification till the end.
