Videocon D2H — They are demanding fee for attending the setbox correction.

My Videocon d2h id no is 87266844. My name is GVS Prabhakara rao. My set box is giving frequently flickering and the programme is getting stopped abruptly. Automatically it is again getting started with in about 15 seconds and going t home channel. It is happening for the last 4 days for atleast 5 to 6 times a day, especially in the mornings and evenings.. When I contacted Customer care, they said to make some internal adjustments. But no result. They are demanding Rs. 150/- to make a visit to my home and to rectify the set box problem. They are saying that my warranty is expired. Why should I pay for the setbox correction, which is installed by your company. Is it not your responsibility to keep the programme delivery intact, so long as I am paying my subscription ?. What is this warranty in between?. I am not going t pay any amount, so long as I am paying my subscription. If you also say that I have to pay for the visit, I wud have no option except to switch over to some other d2h. Thanking you, GVS PRABHAKARA RAO.
