YouWin Withdrawal Problems: Deleted Accounts and Missing Bonuses

They took my Youwin winnings hostage when I tried to withdraw them and out of nowhere, they asked for documents. I followed their instructions, but then they accused me of someone else using my account and immediately deleted it, keeping my money. I complained about several Gmail accounts to Şikayetvar, but they just dismissed my complaints and told me I don't have to explain anything. They say they have the right to do this. Just imagine this - I go ahead and open an account, and then they accuse someone else of playing on it. So, how is this mysterious 'someone else' supposed to take out the money? They want my username now. No problem, let me give it to them - they got rid of it a few months ago, but my username was aliderya766.
