Reliance Broadband
Reliance Broad band did not return my deposit and extra money paid for cable

I was using Reliance Broadnet for few months during which the service was pathetic. After many follow ups it did not improve. I used to pay bills in time. When I surrendered my connection, they immediately took the cable and the dish back. They did not send me the bill and also did not talk about the deposit and extra money I paid for the cable. Also their service person used my mobile for fixing up the issue. Now reliance has sent me legal notice to pay the remaining amount. I want first my deposit and the extra money back and then I will pay the bill or they must deduct that much amount from the total bill of Rs. 2018.66
