Money sent but cant find it on chain..

Hi everyone, someone sent me usdt from binance to a wallet. they stated they sent the cash (gave me a accomplished screenshot but didnt really take note of the txid) but on the improper tackle however even at the mistaken tackle i can't see the transaction or the stability on chain.. I didn't save the txid which i know silly me…. however when i checked the pockets stability and that i checked on bscscan or etherscan i can't discover the cash even on the flawed handle.. do you assume they actually despatched it? or they never sent it but just stated its the incorrect tackle? i have checked all sort of chains… i can't contact the individual now to ask for a txid..
