Is this a scam? How can I recover my money

I participated in the activity and was told that I could be offered a rebate after depositing a certain amount of money, but due to my lack of funds, my boyfriend helped me to store the value abroad. As a result, I said that the third party could not store the value, and then closed my withdrawal channel to freeze my account, and I needed me Make up the security deposit before 6/10, otherwise the money in my account will be deducted as liquidated damages until the account balance is deducted. Who can help me?
