Asus India — Delay in Servicing Laptop

So, I buyed laptop on 13 December 2021 from Asus Exclusive Store, Phoenix Plasio Mall, Lucknow, After 1 month o[censored]se, my laptop switched off automatically on 27th Jan 2022 and didn't switched on after trying many times, upon calling the gwalior service center they took 4-5 days to send engineer to jhansi which is so much time, then the engineer came on 2 February 2022, they weren't able to solve the problem at my home, so they took laptop along with them and told to deliver within 2 days, i.e 4th Feb, its 9th February today they aren't able to deliver it till now also they are saying will deliver in 2 days each time, I ask. Currently my Semester exam is also going on of Indian Institute of Information Technology, Lucknow, and I am facing a lot of problem without laptop, Please do immediate actions ASAP or I am going to take serious actions, against selling faulty product.
