My problem is almost identical to this - https://www.ozbargain.com.au/node/406850 - unfortunately i sqw it too late.
Anyway, i sold a digital game ccode via ebay around midnight, the payment via paypal went through quickly. I then got sent an email from paypal saying "payment reversal has been requested as the payment was apparently made without the account holder's permission or was an error".
I sent the code to the buyer via ebay messages around 8am (i hadnt checked my emails yet unfortunately).
Anyway, i have gone into the redeem option on the microsoft website and the code hasnt been used yet. I assume the buyers ebay was hacked, but is it likely "still" hacked? Did the scammer ever get the code since there was an 8 hour delay..? Should I get a new code via xbox to cover myself? Anyone have something similar happen? CHeers
Get a new code if you can and don't sell it on ebay or using PayPal
