A Really Weird Bug, Need GM assistance.

Okay so i had an m4a1, and just reach my level, i decided to get an ak47, but only had 33K so i sold my M4, in order to purshase one.

Then i go to mall i Click Buy Ak47" - it lag for 3second, but it say Item in bag 1 blahblahblah
So i go and join a Game.


Suddenly i realise it an Ak74, But i Clicked Ak47 foreal.


So could i get an GM assistance for this? like he could take 3K from my account and trade ak74 for ak47...


because yeah.. that suck's..
