HP

My laptop stopped working on 14 september 2017. I called hp customer care for assistance on the 15th. Because of being unable to provide required technical help on phone, the team assigned an engineer to visit me and fix my laptop as it was within the warranty period. They said that the visit happens within 48 hrs. But when there was no such call from the team i called again to check on the progress of my case inly to know that there were some warranty issues now. According to them the warranty had expired on august 14th but according to me it would expire in december. They asked me to send them a snapshot of my bill. I could only find a chalaan copy of the purchase of my laptop and showed the. But as it couldn't suffice the need, i was asked to get another invoice copy from the dealer. I did my part and produced the copy the next day itself. It has already been 5 days but there has been no response from the hp team with regard to this issue. I don't even know whether the invoice copy produced is satisfactory or not. It is me who calls everyday to check the progress of my case only to get one more false promise of getting a reply soon. The case remains unresolved till now and the customer is paying the price for no fault of her in all this.
