[Resolved]  Airtel Broadband Connection — Billing After Disconnect Airtel Broadband connection

Hi,
My Name is Sankar. I have used Airtel Broadband connection for the last one year. Airtel Account No :13807004 .
I have paid the billing amount regularly. I want to disconnect it because of moving to out of country. I have checked with my nearest branch. They said that, if I will give the cancellation form with Telephone instrument by person, they will disconnect it on the same day. So I wont get the next month bill. If i didn't give instrument (phone and modem), then it will take 7 days.

I agreed with them and surrender all instruments and give the cancellation form on 23rd May (Attached the surrender form). My Airtel billing date is 26th - 26th. I have confirmed with them 2 times, i wont get bill for June.

I have paid the May month bill properly. Now they sent a bill for June month, I asked them why did you send after disconnection. They said that they disconnected on July 22nd only, thats also not paying my bill. So they asked me to pay the bill.

Let me clarified, I have surrender all of the instruments on May 23rd and asked them to cancel the connection. They didn't do their work and asked me to pay for their mistake.

Is it the way Airtel running? Can you help me to get a proper answer from the Airtel responsible person?

Thanks,
Sankar
