Received payment from a third party, released USDT, and now my bank account is restricted

Hello everyone,
I’m in search of advice from people who have skilled something comparable with Binance P2P, particularly in Poland or the EU.
I bought USDT by means of Binance P2P. Before making the cost, the customer informed me that the cash would come from one other individual’s checking account. I acquired a total of 1100 USDT (four,325.02 PLN )from a 3rd get together, and after receiving the cost, I released the USDT to the customer.
The customer didn't explain whose account the cash would come from or why a 3rd social gathering was paying.
Later, I used to be knowledgeable that the third-party sender had requested a return of the funds. My bank, Erste Bank Polska, restricted my access to online and cellular banking. The bank then sent me a letter referring me to the District Prosecutor’s Workplace and mentioning a case quantity.
I've contacted Binance help and emailed the prosecutor’s workplace, however I’m still waiting for clarification.
I’m fearful that the third-party sender might have reported the switch as unauthorized or fraudulent. Might I be investigated despite the fact that I launched the USDT to the customer after receiving the cost?
My questions are:
Has anybody skilled an analogous third-party cost situation on Binance P2P?
Did your checking account get restricted after the sender disputed the cost?
