Metamask- Binance Transfer

Hey all.

My friend sent me some metamask from his binance acct. but sent a little too much Ethereum – so i decided to send it back. Before he had a chance to send me his address, i just copied the address from the transaction sent from him and sent it back to that address – but he then said that wasnt his address…..does anyone know what to do here? if i click on the “to” tab in the “to and From” section – it comes up with “Binance 16”

Thanks for your help
