Money sent but cant find it on chain..

Hello everyone, someone despatched me usdt from binance to a wallet. they stated they despatched the cash (gave me a completed screenshot however didnt actually pay attention to the txid) however at the mistaken handle but even on the mistaken handle i can't see the transaction or the stability on chain.. I did not save the txid which i do know stupid me…. but when i checked the pockets stability and i checked on bscscan or etherscan i can't discover the cash even at the incorrect tackle.. do you assume they actually sent it? or they never despatched it but just stated its the mistaken tackle? i've checked all sort of chains… i can't contact the individual now to ask for a txid..
