Sun Direct — Deficiency in Service.

I have been watching Sun Direct channels through Standard Definition Setup box. Recently I have purchased Sun Direct HD set up box. But screen is shrinked after availing HD services.. In spite of so many complaints problem was not solved. Hence I once again shifted to standard definition package. But package is activated to Smart Card pertaining to HD setup box. Still the problem persists. My request to carry over the balance to standard definition set up box from HD setup box was turned down by the Sun Direct staffs.(Both the set up boxes are registered with my name and phone nos.) Whatever complaints I raised the same was closed without resolving the problem.
