Airtel — network issues and poor customer care service

Address:	Bangalore, Karnataka, 560001
Website:	airtel

I had purchased airtel post paid wifi router device in. bangalore 5 months back and for the last 4 months i am facing network issues. Inspite of complaining multiple times to customer care they are least bothered to even respond properly. I am tired of calling and mailing to customer care, they shamelessly hung up the call. Had given application for its disconnection which is also still pending for months now. Month on month they are adding on the amount and almost 52 GB is still left in my account which is dead waste coz of network issues. Please help me . I would suggest no one to go for airtel. They have worst network and worst customer care.
