Aaron Cable Service - Cable operator not showing free channels

My cable operator stopped many channels last month. We tried to contact them many times through different numbers. But didn't receive the calls. I sent them an SMS. Tried to resolve by contacting DEN cable customer care. They also didn't help. We tried to contact them for * weeks. They stopped even the free channels later. And on the date of payment, they came for collecting the payment and when we asked them about it he was blaming the government for the issues. He asked us to fill a form for channels required. We just selected sports and our regional pack. That cost us double the amount we were paying earlier. He collected next month's payment in advance and promised to activate the connection the next day and we are not able to reach them after that. The situation remains the same. First of all, they are looting the people with these regulatory changes which were supposed to help the people of India and secondly they are taking money from us without giving any service. Please provide a solution for this. I am trying since morning to reach them.
