Airtel — restricted outgoing calls, poor services and unreceptive staff.

I am an airtel prepaid user and my phone number is [protected]. Airtel has for the past week restricted my outgoing calls for absolutely no discernible reason. Over the past week i have complaint to airtel multiple times over twitter and through their app making them aware of the problem yet while fixed for a short period in the middle the problem relapsed all over again. Further i bought the 4g connection and i even changed my sim as per their request yet the reception in the area i live in i. E. Nangia park delhi is terrible. I can't surf the internet at all.
I expect a satisfactory permanent solution to help me reconcile my expenses with the services provided by airtel.
