HP India — display issue not covered in extended warranty

Address:

Thane, Maharashtra, 401208

I had purchased hp pavilion x360 convertible 14-ba0xx on 15 september 2018. I also purchased two years onsite extended warranty. On 16 september 2018, i noticed a white spot on my display. I contacted hp support accordingly. They said that the white dot w=is due to physical damage and it will not be covered in warranty.
I am very sure i have used my laptop with utmost care. My previous hp laptop also had developed displayu problem just few days after one year. That time i had not opted for extended warranty. That time it was vertical line. Hp advised replacement of display which was rs 6, 000 for rs 30, 000 laptop. Hence i purchased a new laptop trusting hp.
Hp support are reluctant and they say that the white dot is due to dead pixel and considered as physical damage. Their policy does not cover this issue.
They further told me that it is written on their website which i shoul have read. Now thats where i feel bad, entirely i am held resposible.
I dont understanf then what is the use of me purchasing the extended policy.
I have purchased three laptops in two years from hp. Now i am feelimg i am losing trust from hp.
