bought a key from him turned out to be fine for a couple of days. Then when I had a COD4 match the key was suddenly in use. Confronted him he just said he would look into it... I do not know how he would look into this situation.... And this usually happenes at night so....
A. The key is being used by his also, and he was just trying to get some money and at the same time use the key untill he got bored
B. He sold the key also to someone else from a different time zone or even a different country.
If you are looking to get COD4 for competitive use and really going to play for a long period of time DO NOT GET HIS KEYS!!!! if you want to pub for like an hour and not play untill the next day then go ahead
But the deal was originally that the key was UNUSED OFF THE BOX
