Airtel — useless call & internet services

Address:

Miyapur-Gachibowli Road, Hyderabad, Andhra Pradesh, 500049

I have written multiple times but Airtel customer care people are giving the same senseless excuse for past many months. And still I am not able to use their call & internet services at my place but they keep on charging every month on time.
They show false advertisements for the fastest network & even claim to provide the network in some remote areas, but I am not getting their network at the place where many people live. Airtel is cheating by people by giving wrong information & false claims. So this company & its promotors must be booked for cheating the public.
