Now you are trying to force them to pay you something. How ethical is it! You don't have any valid accusation against them. The mistake was done by you as you ignored their terms. Your total deposits were 6.5k USDT, and you have withdrawn 10.8k USDT in total from your account. So, Punt.com doesn't owe anything to you. If you really think that the mistake wasn't from your side then complaint to their license authority.
