Reliance Bigtv — installation not done after 45 days

Dear sir,

I am shinu. My email id is [protected]@gmail.com.
I had pre-booked the reliance big tv installation by paying rs 499 on 2nd march. My booking id is 12520435. During the per-booking the condition was that the installation will be done after 45 days. But i have not received any information or intimation from the company so far other than the message for successfull prebooking.
Today i spoke to a customer care executive in the no [protected]. She asked me my booking id and told me that the installation will be done after 2 to 3 weeks. I asked her for a definite date but she did not provide that. I also informed her that i cannot wait any further and told her to refund the money paid. She refused that also and cut the call. This is totally annoying.
Consumers like me are taken for a ride. I request you to take this up with appropriate agencies. My only request is that even if i loose rs499 please warn other consumers to not fall prey for such dubious offers of people like reliance big tv.
