This user "chevypart2011" bought an Unlock Code for a Sony VAIO, a Onetime Password which is generated from a 16-character KEY (is decoded from it), after he got his computer unlocked then claimed that the password did not worked, we asked to send another KEY and he just made one up, after that opened up a case: "buyer claimed that the item didn't match the description". When I asked the buyer for proof (a video) in order to issue a refund, he opened the case on eBay, never received any proof and eBay issued a refund to the Buyer.

As of today I have sold more than 110+ codes and all of them have worked.
