Airtel — airtel digital tv refund

Address:

Mumbai City, Maharashtra, 400101

I have requested airtel customer care to discontinue my dth connection on 10.11.2017. I had already paid for the entire 1 year subscription. They told me that hd box would be collected by their staff and i will get proportionate refund. Since that time i have called the customer care no. Of times. Every time they are saying that i will get a call back. Neither i received any call nor any one turned up for collection of box. Registered contact no.in connection [protected]
