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

Hello everyone,
I’m in search of recommendation from individuals who have skilled something comparable with Binance P2P, especially in Poland or the EU.
I bought USDT by means of Binance P2P. Earlier than making the cost, the customer advised me that the money would come from another individual’s bank account. I acquired a complete of 1100 USDT (4,325.02 PLN )from a 3rd social gathering, and after receiving the cost, I launched the USDT to the customer.
The customer didn't clarify whose account the money would come from or why a 3rd get together was paying.
Later, I used to be informed that the third-party sender had requested a return of the funds. My bank, Erste Bank Polska, restricted my access to on-line and cellular banking. The financial institution then despatched me a letter referring me to the District Prosecutor’s Workplace and mentioning a case number.
I've contacted Binance help and emailed the prosecutor’s office, but I’m still ready 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 released the USDT to the customer after receiving the cost?
My questions are:
Has anyone skilled an identical third-party cost challenge on Binance P2P?
Did your bank account get restricted after the sender disputed the cost?
