Airtel — False Bill for Internet Dongle [protected]

Address: Kolkata, West Bengal

Hi, I had given a request for cancellation of Dongle on 11 March 2015. I had received communication from Airtel on 12 March that it will be cancelled by 23 March and monthly rent will cease from 12 March and I have to pay the bill to be generated on 26 March. I had paid the Bill in the April 2015 in due date. However I have again received a bill on 27 April and I replied airtel for this error on 30th April. Airtel customer care is not responding properly and saying it was not cancelled so I had pay this bill as well and also writing that 30th APril is cancellation request date. I had complained to Airtel Appellate authority. They are taking the same stance. In spite of my several email they are not resolving it. If I don't pay the bil then after some months they will raise legal notice. They must be doing this cheat with lot of people. How to take action against these sort of illegitimate activity of such big organization having large customer base. Please help.
