I have been using Airtel from last 7 years. And the service, the recharge offers, the amazing network are the best thing of airtel.
But nowadays even in citys outerside area the network is gone then how I can think of complaining about the remote areas where too the network availability is zero. After several complains too, they are not fixing the network issue in my area.
As they are going on increasing prices, they have forgot to maintain the quality of their network in each and every place. No doubt when the network is available, no one can beat the airtel 3G & 4g network. But the problem is network availability.
