Den Networks — not providing channel selection form

Address:

sector 17 airoli navi mumbai, 400708

My cable operator (Adi shakti cable network, airoli navimumbai) is operator for den network and is not providing form for channel selection even after asking for number of times. They always give reason that forms are not available. So every month i have to pay fees as per old price which costs me more. So please tell me how can i solve this problem.
