Dear sir,
My airtel mobile number is [protected]. I'm facing a network issue for each and every day. There is no speed in data speed. Hardly it was 0.5mbps. I gave alot of service requests. But they are saying we are expanding our network. Then why are they saying it is 4g and make a advertisement as airtel 4g. Hardly 2 months over there is no network download speed to watch movies play games. They simply said network upgradation work on process. I asked about finishing date, for that they said don't know aboyt that. Please make a proper action on airtel.

Yours sincerely
