Videocon D2H — Didn't get warranty

Address:

Pune, Maharashtra

I paid ₹499 to their engineer for warranty extension but he recharge my account instead of warranty extension. When I called him he said your warranty recharge is done.. But didn't get any channels which was in the offer but my account was recharged with ₹499. And now when I called in CC for my remote issue they said my warranty is expired.. And I used ₹499 so I have to pay again for warranty extension.. I just wanna know why should I pay again ₹499 for warranty when I already paid for that and their engineer told me that my warranty is extended... That's not my fault.. Its their engineers fault.. I thought instead of providing channels they recharged my account.. What should I do?? My Cust ID[protected] NAME- Sudeep
