HP Laptop Warrenty
Warrenty Extention Problem

I am having a Laptop of Compaq. I have extended my Laptop's warranty for 1 year by HP Warranty Extension Scheme. Due to mess communication by HP Customer care executive my warranty extends just for 4 month instead of 1 year. As I quires about at they told me that you have to submit your laptop's fitness certificate. After that i have done it. But it is a very long period of 4 months they do not give me certificate of correct date. I am doing regular follow-up to HP but they are not giving proper response now.

Please help me
