Airtel — Airtel Broadband generating bill eventhough i requested for cancellation

Address:

Bangalore, Karnataka

Hi sir,
This is Sunitha from Bangalore.I was having an Airtel Broadband connection from last 2 years.
After 2 years I asked for transfer of connection to different address.It got shifted.
After that I asked for cancellation of Broadband service in the month of February 2012.I paid the total outstanding amount 2779 (Invoice no:[protected] and reference no: 421467 ). and sent an email to airtel stating the same.
I informed the same to customer care too.But they did not cancel the service and keep on generating the bill and yesterday I received lawyer notice for the same.Why should i pay the bill even i informed Airtel to cancel it. Yo can check whether any activity is there in that period of time. Landline number is [protected].
You can reach me at [protected].Please help me with this.

Thank you,
Sunitha
