Binance complaint: Binance P2P Overpayment

Hello good afternoon, I am laying a complaint because I overpaid a btc vendor on binance who goes by nickname “Tadese” the order number is (20249622869883846656)
I paid N172,987 by mistake instead of N136,987 yesterday July172021 on Saturday morning 8:58am.
This seller promised to refund me saying I have to wait for him to look through, then he agreed that he got the money but I never got refunded till now. I filed an appeal on binance and support said I should wait 48 hours and if I don’t get refunded I should check back. This afternoon I sent the vendor “Tadese” a message while I opened another trade for the amount I overpaid so he can refund me with bitcoin but he said I should cancel trade and message him in whatsApp so I did but then I got block, luckily I didn’t cancel the trade. Now he filed an appeal against me saying he never got any payment. The second trade Order number is 20250031903824498688.
