I was a customer of airtel for very long time but after lots of suffering and disappointment I ported my mobile no. to other service. They never cared for their user all they cared about their profits. Sometime they even deducts the balance from user account without their concern and the offers they provide to their user is quite expensive and for very short period of time. For eg they 5 gb for 1 day in 199, tell me who would take this offer, we people uses internet for daily works not for one day. Because of all this I didnt like this network service.
