Airtel — Service and network related problems

Airtel aap and airtel services are the worst i have ever experienced no internal network no proper voice calling network cant even get 2g network easily. Facing too much problem for the network i would suggest no one should use airtel now onwords. They are just creating fake publicity and marketing campaign which are promising fake services. Rest all this they even dare to xharge customers for late payment but they dont want to give customers the promised service which they are get paid in adv
