So some guy off ebay bought my product back on June 1st. I shipped the product with tracking and it was successfully delivered. Nearly 40 days later (July 9th) he opens a PayPal chargeback case claiming unauthorized charge of his credit card. I provided paypal with evidence they asked of me. July 22nd, Paypal closes the case in my favor and said in an email that I met the requirements of Seller Protection, money was given back to me, case was closed. Aug 4th, the guy's card issuer files a counter-claim Aug 4th, paypal reviews Aug 4th, case closed again in my favor Aug 6th, another counter-claim received by card issuer Aug 6th, case under review (again) ....so, what the heck is happening here? Is this some case of a guy spamming and trying to chargeback even after the case was closed twice by paypal? Paypal already told me it's done and the transaction met eligibility of Seller Protection, so can I assume that I'm safe still? Or can they completely go back on their word and take the money out again? It seems this person or the card-issuer of this buyer is trying hard to dispute and dispute and I don't know what new information they are trying to provide each time to find a loophole? This concerns me and sounds like the work of a scammer. Should I be concerned or is this pretty much going to be rejected everytime they keep filing a counter claim?
