Airtel — active my number

Address:

Bangalore, Karnataka, 560066

I have been using airtel sim past 7 years. Accidently i have not paid 3 months bill. Now they deactivate my number (Without giving a information). I have asked them several time in that time they said okay we will activate. But still the card is not activated.
I have been contacted your customer services but the executive doesn’t give satisfied answer. Even am ready to pay all pending bills. Please activate my number. That number i have attached all my personal accounts. The present situation is gonna am not able to do any work without my sim.
So stop this harassment and help me out.

Note:if you not help me i am going to complaint to customer forum.

My number is: [protected]
