Dell India — dell inspiron 7460 issues

This complaint is regarding dell inspiron 7460 laptop bought in 2017.
This was purchased as an official laptop for the head of the department (Indian audit and accounts department). Right from the day one after the purchase there was some or the other problem with the functioning of the laptop. Many a time issues were raised and they provided us with only temporary solutions saying that it was just a software issue. (The frequent issue was intermittent autoshutdown). Of late, as the laptop has become out of warranty and when approached the service center with the same problem, they said many internal parts have to replaced and that would amount to almost buying a new laptop. When enquired, this particular model seems a failure and has been posing many technical issues. The response from the dell service team is not up to the mark. It is ridiculous to spend such an amount on a failed model just for the excuse of naming it out of warranty.
