Lenovo — not getting any help from lenovo

1) i am not getting any response from any
Of their customer care email address.
2) when i go there website to get my
Product support, website wants my
Serial no, model no, iemi no of the
Product, but it's strange when write all
Those think they want, website says
"sorry there are no such type of
Products". I have tried several times
But answer is same.
3). When i go their website to find service
Center around kolkata, website asks me
To log in. I failed to log in after several
Attempts.
Above facts show that lenovo, india
Is not willing to provide any kind of
Service after sale..
