Worst network in India.. their customer service is very lousy, I have been telling them gazillion times to rectify their shitty network they are giving trillions of different reasons and I ported to Airtel recently in that process they kept spamming me with upto 10 messages and 20 calls a day to say not to port. Also they charge additionally even after paying the bill... They do not have answers to any of the queries raised.
