HP India — I am in lots of trouble.

Hello,
Let me explain all the issues and resolution I have faced till now.
Lets begin from the very beginning, In the month of July, I submitted a case in HP. The issue was my laptop was constantly freezing whenever I used to play games or to do multitask. I have a gaming laptop. The service centre team and the service head team helped me by replacing the HEAT SINK of my laptop. After replacing the part mentioned above within a month I again encountered the same issue, which was freezing. I again submitted the case and again the engineer came with the same part i.e HEAT SINK. Just after replacing within 15 mins my laptop faced the same issue while I was monitoring the laptop. I again called back and told them the current scenario so they told me to submit the laptop. But I was not in the condition to go and visit service center so I requested them to please provide on-site service. Untill now my laptop was properly functioning apart from the freezing issue. Now after requesting the onsite service engineer came with a new motherboard. After replacing motherboard my laptop didn't turn on. The engineer informed me that it might be a motherboard fault. He again visited within two days with a new motherboard. After replacing the new motherboard my laptop didn't turn on again. I mean whenever the engineer tried to turn on, it started the booting process with a hp logo on it and then suddenly it goes power off. After inspection he told me that there is a issue on your power button and a cable with is attached to it. He informed me that it won't be covered in warranty. But however as earlier my laptop was in working condition they exceptionally included in my warranty. The engineer again visited with a new part that is power button along with cable. Even after that the laptop was still giving the same issue. That is it was automatically getting shut down. After that he informed me that I need to submit laptop in service center. My father was in hospital still I visited service center and submitted my laptop. They kept my laptop for one and half day. After that when I brought my laptop at home it worked properly for a day. After one day it again started with the same issue i.e it automatically gets shutdown or screen goes blank. Now I have explained all the events which have took place from past months.
Main part :- The complain was regarding freezing issue which is still not resolved and now my laptop has another issue which is it goes blank screen or it just shut down automatically.
My laptop is being operated or opened more than 5-6 times. Still the issue isn't resolved.

EXPECTATIONS :- As I have mentioned above I am facing the issue since months and still haven't got any resolution. The issues are recurring every now and then. My laptop is being operated multiple times which according to engineers and experts is a bad thing. The issue should've been resolved in the first place. So my expectations from HP and Its respective team are that I want my laptop to be replaced as because the issue is recurring and now the laptop has become much more worse than the previous condition. I want a replacement as because I have suffered from months. I have suffered in various ways for eg. Studies, Jobs, etc. Even though my father was in hospital I still visited HP service center in hope that they will fix my issue but unfortunately they couldn't. Multiple parts have been replaced and still the issue is not solved as well as a new issue is created which was not there before. So its a request to HP and its respective team to kindly see through the problem I am facing from months and please provide a replacement for my laptop. I hope you can understand the issue. Hope to hear from you soon. Thanks and regards.
