I had to pay an invoice today to a previously unknown party. My bank sent me a SMS to verify a new payee and then an email to follow up.
It's possible that is what he forwarded you? It might be possible something similar could be done just by adding the new payee without paying but I don't know.
Bank transfers are fairly quick these days so mine isn't even pending it is marked as actually transferred immediately but I guess that doesn't mean it has been credited to your account IDK
