Sun Direct — sun direct connection number [protected]

2 weeks back, i complained about overlapping pictures and technician told the problem with set top box and needs new one. He changed it. But problem same and continued. Now he said the problem with tv.
When the problem is with tv, why i should pay for a new set top box???
He has taken both old set top box and new set top box. Now since i do not have any connection, i request you to refund the advance i have paid for 3 months, immediately.
If this is not the right forum, kindly let me know to whom i have to contact, in this read. I was very particular to put only sun direct. But, i have cut a sorry fighure in my family.
