Lenovo — Lenovo IdeaPad s340 product replacement serial no. MP1QJEL3

I bought this laptop in march. I was facing battery issues since first month. I tried contacting them but their phone was busy all the time.
I raised a ticket then, they called me back and did the calibration thing.
And closed the ticket without futher confirmation whether it's working fine or not.
I raised another ticket but i did not get any response.
Had to wait another 15 days for a call that said reboot your windows.
Did and still faced the issue.
Went to service center, they said battery issue, got my battery replaced.
Afer 15 days of thorough checking i was still facing the issue, they asked me to reboot window and check again. After another 15 days i submitted the laptop. And then he sent me videos saying he checked it it's working fine. Went there to check and collect today thay is 21.11.2020. It was still not working fine and they said "itna to chalta hai". How come "itna to chalta hai" when this is a new laptop and I have been facing issue since I bought it. I have spent 50 thousand of my hard earned money. How can they say itna to chalta h ap le jao ise.And it has been 8 months that I have been running around for this same issue.

I need a new product because I am pissed now. I don't have all the time jn the world to go and check for the condition of the laptop every week. I am a working professional.
Hence i need a new laptop as a solution now. I cannot work with this issue anymore. They are not giving me satisfactory replies and service.
Also while i was checking, the battery after replacement, it's camera had some hardware wiring issue for which I had to again raise a ticket and was not contacted in time and had to go to service center again. I have visited that center about 10 to 15 times in 6 months just for this single issue. I have all the video proofs that i sent them as well regarding the issue. And they all have dates mentioned. I have all the mail proofs that i sent them related to this issue and did not get a satisfactory response.
I have copies of all the tickets as well.
Also they have all this tickets that are still in progress because of which i cannot raise a ticket again because according to their system, until unless a ticket is resolved we cannot raise a new ticket.
The link to all the proofs can be added if required. As there are a lot of videos and pics i have them in a separate folder which cannot be attached here.

Lenovo IdeaPad s340( I don't need a satisfactory service now, i have wasted my 7months of time and energy on this ### product and their ###TY service. I need a new product as replacement (new laptop basically) and an apology for their poor service)
