Hire a certified ethical hacker

My problem is as following.

I attended a group titled of Binance BSC smart contract project.

We can send three times ETH to a smart contract address, and to get BNB back, every time 10-15% of ETH value.

And the first and second time, we should send at least 0.3ETH. The third time we should send 0.45ETH.

I got BNB back at the first two times. But didn't get the return of the third time. It's still stuck in the contract address.

I questioned customer service, said, I should market BNB OVER in Transaction Data as remark so can get it back. Then I asked how to solve it, they said I should remit another 0.45ETH marked with BNB RECOVER. So it can be activated.

I thought it is just a lie.

And I really want this money back to my TRUST WALLET.

I can pay 0.1ETH to you, if you can help to get it back for me.

Below is the information.:
TRUST WALLET address: 0xD93b49D288858376428665F4C947dA5771d40251
Smart contract address: 0x0Fe161eB79c73BA6B7C5347362C0e8aB29c7cDbA
Block namea: 14485528
