HP India — Claiming warranty for monitor

I bought a monitor "hp 22f" on 03/06/2019.
It started showing issues from 08/09/2021, so I sent it to the store where I bought it from, and as it was under the 3 year warranty period, they promised me to return it within 10 days.

Now it has been about 38 days, and the store tells me that no personel from hp has come to repair my monitor. It is clear that buying an hp product was my biggest mistake. hp prioritises profit over customer service.

I am a college student, and I have been facing many issues without a monitor because I used that computer for my online classes and online tests. Just how irresponsible will your customer service be and how long are you going to test my patience?
