Airtel — postpaid problem

Address:

Jammu, Jammu and Kashmir, 180003

Network problems near Jammu airport (satwari cantt ) my airtel postpaid number is [protected]. Previous months here was very good connectivity on airtel.but now not get 4g, 3g, even 2g. What we do sir. My number was ported bsnl to airtel. When that time airtel has good network in this area. But now very poor connectivity in this area. Airtel stopped a tower in this area. Is it cheating sir. So I want to return my previous postpaid bills amount.
