Lenovo — laptop damaged in service center

Address:

Pune, Maharashtra

I gave the laptop for service in lenovo registered service center located at fc road, pune. During service they damaged the laptop screen, which first they didn't accepted but later accepted and told me they will replace the laptop screen. Laptop was under warranty.

My concern is/was - if service center has damaged the screen which is physically visible then there is a chance that they have done something else also to the laptop and as laptop is damaged by them then why should i accept the repair? I asked them for machine replacement. They didn't agreed to that.
I dropped countless email to service head of lenovo india, but i didn't get any resolution. All they say is, we can't provide the replacement to you.
Laptop is in service center from last one month. I'm not accepting the repair and they are not providing the replacement.

I have clearly told them laptop is damaged by you, i will not accept the repair, i want replacement but they are threating me by saying collect the laptop from service center, lenovo will not be liable if any further damage is done to your laptop.
