Acer India — Technical Engineer (Destroyed my Laptop)

Address:

Flat 18, Plot B9/12, Akanksha Appt, Sec-62, Noida, UP

My laptop stopped booting on 14 oct
An engineer from acer team (Quest Infotech, Laxminagar) came to my house
He corrected it, But installed firmware/bios update which I even told him not to do.
After that my laptop motherboard crashed, and it was replaced 4-5 times
Very recently on 13/11/2021, when he got to know that he had destroyed the bios through that update,
He took laptop and gave me back after few days
Now laptop has refurbished motherboard, Not a new motherboard which typically works for very long, And Laptop has become so slow I cant really do anything productive on it

Very Dissatisfied with your services
