[Resolved]  Airtel Data Card — Too slow Speed of Airtel Data Card

I too am facing the same problem from more than a month. I am fed up of calling Airtel customer care regarding the speed issue. Every time they give a new date for fixing it. All false promises. After I told them that will not pay the bill since i didn't receive any service from them, I got good speed for 2 days. But the moment I paid my bill speed vanished. Again it has gone down to 0.00KBPS with which it is practically impossible to work. Now I again tried to call Airtel customer care, and twice they disconnected my call without listening my complaint.
Please resolve this issue or refund my money.
