I have purchased a laptop on 31st december 2020 with model name ideapad L340-15IRH Gaming. Device name Laptop - AIMH512. As resq plan of reliance I have also taken 2 years additional warranty. Now the laptop is having an issue in charging port. On 19 August 2021 I have given my lap to an athourised service centre, Regenersis Prime Digitronics Services - Lenovo Service Center) in Trivandrum. Till date I have not recieved my laptop.
This service centre is nearly 75 KM away from my home town.
I tried to contact the service centre on telephone many times and the answer is we will contact you later.
As per my request my friends who are in the local area approached the service centre, and the result was same that is we will inform you.
I am a BTech student who purchased this laptop for my studies.
I regret to inform you that the response from the service centre is too poor, very bad, ugly, sprious etc.
