Had plan on "vacation" since December 2015. Modem is unplugged and yet data usage shows 0.6 GB used. Underneath it says 12844% used of 0 GB allowance. More creative accounting by yet another rip off company?
Same thing happened to me. Upon calling customer service, I was told that the total used was from before we had it put on vacation and it would be re-set at the time we reinstated service. Follow up on this to be sure it is re-set!
