The first time they fixed mine it took around 3 months...which was a gyp because I had just used a 1 month which got completely wasted,  as well as taking 3 months away from my current account at the time.  So now I am going about replacing the one I have now, and it took them a week just to send the box, which got damaged in the mail, so I have to wait another week and call them again so I can get a new box.  I have such bad luck.
