No, i made deposit 501 usdt, claimed 500 bonus. Then i played a lot of slots games. I finish all wagers and won about 4280 usdt. Only then i tryed to withdraw
judging from the report you made on scam accusations, you do have proof of transactions, but do you have screenshots of evidence such as chats with support or screenshots of your withdrawals on your Wintomato account?
if you have screenshot evidence, it's better to add it to your report so that it's better and there's no misunderstanding.
An evidence he win the bonus in legit way is the best like game records including all the wins to sum up to his profit. The conversation to the support is good too so that we can determine what is the actual reason why does the casino didnt honor his profit.
A story like this usually involves abused of bonus like using multiple account to claim the bonus until they hit this kind of jackpot win on slot. A 500USDT to 4280USDT turns is very rare to achieve on bonus run in the casino due to the wagering requirements.
