my controller is f-ed

So when I'm playing and I earn a killstreak, as I'm playing usually if I'm heavy on the stick, it will call it in without me pushing the right arrow. I use kontrol freaks, but I've checked and there is no way that they are hitting the button. I had this same problem with an old controller on blops...but there it would pull my claymore out...or sometimes randomly change my weapon. The controllers work fin otherwise, and haven't had any problems on other games.

Anybody else have any problems similar to this? I will probably have to get a new controller...it's probably time anyway as the left stick is getting a little lose.

A loose stick is not fun.
