Someone trying to make binance send my crypto back to them

Hello everyone someone paid me crypto to my binance from a debt they were owing and now they are trying to make binance send the funds back to them saying it was a mistake and they have a screenshot of the transaction as proof from the exchange he sent it from. This guy did the payment over the phone so I have no written proof that he was going to pay me crypto other than the transaction ID after he made the payment. Binance is asking me to return the funds or prove it’s mine. I don’t have concrete proof so how do I fight this ?
