i am a resident of Rohini

sir,
i am a resident of Rohini, Delhi. my cable connection is provided by M/s sam world vision (tele.27947503). the monthly charges are Rs. 350/-. for the month of october also he charged the same amount. whereas it is understood that CAS is being introduced in delhi from 1.1.07, and as per TRAI press release the cable operators should reduce the charges to Rs. 200/- or so from 1.10.06. since the cable operator has not reduced the charges please advise me on the further course of action.
