I do understand your point, all im saying is, the address belongs to OP and does not look like a disposable one. So in the end he received the money
If the address still belong to the OP then this isn't classed as a scam since it's still his wallet / address meaning he still received the refund from the abandoned deal.
This scam report is all kinds of fucked up.
I recon a member of staff should be on teamviewer with OP going through his wallets to clarify some of this information.
Maybe he made a dupe account to do this "deal" to rope Teken into it.
Then sent to addresses on purpose, since I'm guessing he didn't clarify the first address wasn't his and now has the money and claiming he didn't receive it.
Yes undoubted Teken should have double checked but OP still received the money being both are his wallet.
Kinda sketchy if you ask me.
