Sending usdt from kucoin to binance didnt work

Im utterly new to crypto so bear with me please. My brother despatched me my 58 usdt from his kucoim account to my binance account about eight hours in the past. He stated the sending was successful (he checked it on something concerning the blockchain explorer I didnt really undwrstand), but that the transaction wasnt credited to my binance account but. What do I do? When i'm going to wallet on binance then spot then usdt I discover its nonetheless zero

Edit: the best way it was despatched was that we took the qr code from binance and scanned it on our kucoin account. We didnt write down any addresses
