Timbl Broadband — I want refund as not satisfied with their services

I had taken 50 mps unlimited plan for one years From timbl broadband service gurgoan. I paid them 3 days ago and My router was setup yesterday but my internet is not working till now. I have raised my complains and called them several time but nobody is bothered about my internet issue.
According to them internet will start working in an hour. But it has been several hours since my installation done.

I feel cheated. Strict action must be taken against them.
