You just got scammed hard
Transfer all your funds to a NEW wallet and delete that extension, its a stealer.
You might want to even factory reset your pc, just to be sure

If he used the common sense he might escaped from the scam even after the first deposit but now did three time deposit,too pathetic.

If anyone is asking to deposit your money to withdraw their bonus money this is an obvious scam guys,just wakeup and so research before doing any new signups.
