I purchased a laptop of hp from kohinoor televideo pvt ltd from your vashi satara plaza branch which was giving problem initially there was a lining on the screen which was coming. I took the laptop to your store and showed them the same and made a complaint with hp as well.

There was a offer of extended warranty and antivirus protection under back to school offer which was supposed to be taken within 7 days of purchase.

When the engineer visited then the laptop got updated and now the lining is not coming however i am not able to avail extended warranty offer which i wanted. And they are not even replacing the laptop which ideally should be replaced

Pls help
