Airtel — airtel xstream box

Address:

Bangalore, Karnataka, 560078

I have purchased airtel xstream box 5 days back. And it it my biggest mistake. I am not able to stream airtel xstream content. I have raised this issue to multiple times to customer care. And three times to airtel nodal office. They are still not sure that they will be able to resolve it or not. Always they are asking me to wait for 24 hours and not giving any reply on that issue.
I am asking to refund my amount they are also not doing that.
