Hello, for example other trade party sent me SEPA bank transfer in correct amount, maybe even mentioning their name in a transfer note (matching their name in RetoSwap trade details), but the sending account number is different from what they have in RetoSwap.

Please kindly tell me what to do, all the cases and how to handle these cases and ideally why?

For example I can copy paste the transfer detail to the chat and ask the trade party if this transfer is theirs. And if they confirm, I can mark the money as received assuming it causes no risk for me. But what if the party does not respond and the allowed trade time-frame expires?
