[Resolved]  Airtel Bill — no service for payment at airtel outlet & harrasment

I was a postpaid customer of airtel from may 2011 to august 2012 .
I stopped using the number. I called the call center to help me close the service.
At the Thane airtel office they told me not to stop it but they offered me to convert it to pre-paid without any charge this was done over the phone at the airtel office they disuaded me to cancel the service.I agreed as I need not pay monthly charge.
But subsequently there was no conversion of the sim and the airtel call center kept calling me to pay the bill.
please go through the teleconversation where I tod them to send across an executive with the bill and I would settle it immediately.
I tried to pay through the net but it was not possible. as they had cancelled the postpaid number.
I visited the Thane office to settle the issue they said the system was not working and could not help me pay the bill.
There were again call from the call center of airtel. one Mr. Aditya or so asked me to pay the bill , I requested them to send me the bill and I would pay through cheque or through netservice. The person from the recovery centre promised to send a person it was a Monday on ie 1st week of Feb.2012 no one came I kept waiting,
Trace my calls please.
This harrassment has been going on without solution.
The airtel officials do not want to settle my issue at all.
Kindly give me justice.
