Lenovo — Duplicate keyboard replaced by lenovo service center

Address:

61-old cannaught place chakrata road, dehradun, uttarakhand

Sir/ma'am,
My name is akhil kumar from uttarakhand. My laptop keboard was replaced at the lenovo service center (dehradun) on date 12-7-22 and they charged me very high price of 2800 rs. But the main problem occurs when i found out that the keyboard was of poor quality and they replace the duplicate keybord in my laptop. Because the backlight of the keyboard didn't showing any alphabet in the dark.
Please solve my problem as soon as possible the stores behaviour after work is very poor to me.

Thank you,

Regards,
Akhil kumar
