HP India — I am complaining about defective hp laptop received from hp online store

I bought a hp laptop online through hp store. I paid the money online on 16 jul 20. Invoice recd in pkg was of 17 jul 20 and laptop was physically delivered to my address on 20 jul 20. On 31 jul 20 the laptop did not switch on. I talked to hp support through toll free number and then to technical support team hp. After some time while talking to tech team hp and laptop infront of me, the problem was solved. Then on 12 aug 20 the same issue arrived, laptop did not switched on then again i talked to tech support team hp and complain to replace/return the laptop was made. Laptop would switch on after talking to tecnical support. Mail came that engineer will visit soon. But engineer call was received on my phone he asked whether laptop was working. As laptop was working i said yes and also told issues faced. Then agin the same issue faced on 22 aug 20. Then i talked to the engineer whose number was forwarded to me through mail and i stated laptop issue. Engineer came on 24 aug 20 took my laptop to the service centre. After some days he called me that your laptop defective part has been ordered and will be handed to you after replacement of defective part. I told him that i don't want that defective laptop i want new replacement for that. Then he told talk on toll free number. Then i talked to technical support through toll free number each time they would provide me case id and woul tell the case has been forwarded.in the mean time engineer called me that you want to repair your laptop or not otherwise we will return the spare received. I mailed my problem to doa, hp support, inced. Hp and every thing they wanted to know through mail. After fed up by their irresponsible replies i filed complain on consumer helpline (Id 2210461 dt 31 aug 20). I bought this laptop for my child studies but of no use. Doa is replying that unit is out of doa as 14 days has passed but i told them first fault occurred within 12 days of physical receipt of the laptop. You can check your toll-free number call details etc. Same issue not switching on in laptop again and again means that laptop delivers to me was defective. Now i want refund or replace my laptop
