Reliance Bigtv — reliance big tv service very very poor

Address:

Ghaziabad, Uttar Pradesh, 201010

I have been complaining to reliance big tv customer care from the past 10 days regarding problem in my setup box (Complaint no. Given was[protected] dated 18th july, 2017). Even after repeated complaints, i am not able to call further since the customer care no. Says "i have exhausted the maximum no. Of tries for the week". I mailed to them but not a single call from them. Such bad service from reliance. Previously, in the month of may, 2017 my tv was dead for almost 12 days. I want to lodge a complaint in the national consumer forum. Please suggest how to proceed. I have already paid the subscription fees for the whole year and they are not reimbursing the same.
