Airtel — incorrect billing | wrong monthly plan | overcharge

Address:	Gurgaon, Haryana, 122102
Website:	www.airtel.in

I raised a complaint on sep 20th, 2018 i raised a complaint with airtel via email [protected]@in. Airtel.com complaint number[protected] for my broadband service.
In my complaint i addressed the following concerns; monthly charge on my connection was upgraded to rs.1999 and despite repeated requests this has not been lowered to rs.1399. For the poor network service airtel suggested me to install additional router, which was an additional cost to me; the engineer installed the same and charged me rs.1600; still no respite, airtel went ahead and charged rs.900 in addition to the same.
Airtel made multiple false promises of reverting charges that they haven’t done; the only discount i received was of rs.100.
I am holding the payment for two months, in response to my above mentioned complaint; today i received an email to my complaint which stated they have taken the cancellation request (Which i’ve never made) and will not charge to my account effective sep 28th, 2018.

I look forward for resolution to the above concerns, my proposed resolutions are:

1. Airtel to update my monthly bill plan to 1399
2. I will pay airtel the due amount in accordance to the 1399 monthly plan
3. Airtel to refund me for the overcharge on router installation.
