What about my account, why don't you want to withdraw my deposit? And why don't you answer me?

We have released his funds to this user when he contacted us back on May 10.

Can you please explain me what is the difference between his case and mine? Thanks

Our security team has checked your account and found no funds that require to be refunded. Which means a player have withdrawn an amount that bigger or equals to his deposits amount, or the bets were simply lost.
A lost bet keeps its negative value after recalculation if the bet was placed within the rules.
