Lenovo — worst service of lenovo

Address:

Bardhaman, West Bengal

Lenevo company service is too much worst. I done biggest mistake to bought lenevo product.
I bought lenevo ideapad 510 and its mother damage in 6 months only & when i complaint about it then engineers who came knows nothing about your product.
After replaceing the mother board of my system lots of more problem came in my system.
No battery is detected
Ram is showing only 4 gb but it has 8 gb.
And when i call your engineers to complaint about then he talks to me in rough language and cut my call.
