Reliance Bigtv — no service even after collecting the amount in full for 2 years

Address:

We have paid an advance amount of rs2500/- for full two year subscription and after 20 days no channel is available for view including the dd, tried to reach their customer care but in vain, previously we had lost more than 4 months of no telecast of many channels but now they have shut the shop and vanished, looks like this company also is one of fly by night type, pls help us either to get refund or resume services immediately.
