HP India — laptop service spare replacement denied under warranty

Address:

700016

My hp laptop bought from an authorized hp showroom under valid onsite warranty has been denied defective spare replacement (Display screen)

Hp service claims the ct no on the existing display unit on my laptop does not match their records. They claim the display unit of this specialty detachable laptop is not even manufactured by them since the ct no is not matching with their records. I have had two hp services in the past 2 yrs for this laptop under warranty.

They seem to have messed up their records or reading the incorrect ct no on my display - just trying to harrass me and trying to close the case without giving me any logical reason

Kindly assist
