Just because you scammed someone who you suspect of being a scammer, doesn't make you any less of a scammer.
Well from the looks of it, the codes were sent to Wardrick on Jan 25, and the codes went bad sometime prior to Jan 28 when the OP made this thread. That means the codes went bad within 3 days, which is under the OP's current "warranty" and the OP does not appear to have offered to replace the cards.
