I spoke to 2 different representatives on phone about the current issue at hand, it seems that it is an occurring problem they said, as i knew already as i play gears of wars multiplayer in my free time and pretty much nothing else. From what I've read on gears forums i know quite a bit same from what i have found out my self, it is also mentioned on these forums that the issue i am having has occurred before to other players. They have been given the achievement but not the weapon skin. I would like only to resolve this issue in the quickest and if most possible manner. i would like to unlock this weapon skin very much, as it is the only one i do not yet have.
