Airtel — not at all getting 4g service main city only

Address:	Ranga Reddy, Andhra Pradesh, 500047
Website:	Airtel

I am staying in malkajgiri, secunderabad
From more than 4 months i am calling to the airtel customer service that i am not at all getting 4g lte service.
Always the customer service members are say some or the other reason!
I am living in the main city, now only i am not getting the service properly.
What the hell service, i will get if i go out of the station or anywhere in the forest.
The worst ever service and more over no proper response from the company after complaining about the issue.
