HP India — hp laptop - 14s-er0003tu

I had purchase a hp laptop on 9th august, 2020 from vijay sales, santacruz branch. The display of the laptop malfunctioned from 14th august, 2020 due to which a complaint was filed with hp india which was registered on 20th august, 2020 vide case no. [protected]. I was informed that it being a hardware issue the engineer will visit and the laptop will be replaced and a date of 27th august was given for engineer's visit. However, till date nothing has been done in this regard and hp india is passing the buck on service centre.in this regard, kindly arrange to replace the machine at the earliest or refund me the money back failing which i may have to take legal recourse.
The laptop was purchased for online learing in the ongoing pandemic but the purpose of the same is not being served.
