This happened two days ago and he actively responded to my PM explaining things.
Maybe I expressed it in a wrong way. He has (temporary) access to PMs for sole reason to eventually make it whole with me and @JohnnyPotseed (it’s the only communication channel I have with him and he actively responded). I still don’t have a “proof”. He still has a benefit of doubt … until this case is resolved one way or another… That may take a week or two.
I’m not familiar with the card protection processes, but my PayPal says that it’s his financial institution who filed for the chargeback, not him personally. Maybe if he reported the card as stolen or misused, the bank reverted all recent transactions in an attempt to mitigate losses.
But I definitely won’t be letting him to engage in any trade…
