Reliance Communications — Extended warranty

Address:

Chennai, Tamil Nadu, 600062

On 28th May I purchased a HP Laptop. The sales executive offered me an additional two-year manufacturer's warranty apart from the regular one-year warranty. I accepted the offer and paid for the same.
Now after 6 months I am getting reminders from HP to renew my warranty. I took up the issue with them and showed them proof of having paid for an additional two-year warranty. They confirmed that this additional two-year warranty is not given by them. I got back to Reliance Retail store and checked with them. The manager now says that this extended two-year warranty is given by them and not by HP. This is outright cheating of innocent customers.
