Dish + setup box + 2 months free

I booked for SUN DTH to avail the offer of Rs.999/-(Dish + setup box + 2 months free)some where in the month end of December 2007. But the set was deliverd to me only at the end of February 2008.The installation of the same was properly completed on 15th of March 2008. But service was disconnected on 24th of April 2008 (only 40 days) before the completion of 2 months period as assured by SUN DTH. This is merely a cheating. Can the customer care officers will do the needful to rectify the problem and ensure that I get my service for another 20 days for which I have already paid, orelse reimburse my money back and I am no more in need of the service.(My SIM CARD No.4100 9386 362R)
