Please help, can't withdraw

I was trapped by the lure of an acquaintance to invest with a return of 20% in a short time of just 2 hours. The first top up was 3038 USDT, instructed by the acquaintance to trade and make a profit of 600 USD, followed by withdrawing the 600 USD profit return and it went smoothly into my account, then I was offered a second top up. 1500 USD and the third 2739 USD, total in the account 7276 USDT, waiting for the continuation from the contact but until now there is no clarity and I am starting to get nervous because the money invested cannot be withdrawn. I confirmed via CS Online and it was confirmed due to certain conditions, namely the account value must be greater than 8478usdt and do 2x trading, I'm not familiar with trading. I tried with several small amounts but lost. At this time my acquaintance left me. I ask for help to withdraw my money. Thanks.

The following is the original recommendation
