Why don't have? You transfer from your bank account to his, just
check your account statement.
Or if you use cheque also got record.
TS also have seller's account number, can report that
account.
Anyway, how much is it? If it's within what you can forego, then
just let it go and think of it as a bad choice and be more careful
next time. Give him a stern warning though, also try to warn people
who are buying from this guy.
The key thing here is the amount you lost and how much time and
effort you can afford to get it back. No point chasing after a bird
who took a snip off your burger.
I am telling Firelice that bank transfer got records one
