HP India — Missing of CT number of the Display of your laptop key id [protected]

Address:

201 KAILASH APARTMENT,OPP BK NO 1101,NEAR JASLOK SCHOOL

Sir
I have purchased the HP Laptop 15s-eq0007AU 9VX05PA on 17.06.20.
I had found impressions of keys on display which disturbed me to see the display properly and I had lodged a complaint in the month of December-20, against key id no [protected], you had sent engineer from Q-Digi service Ltd. Mumbai and engineer changed the display.
Again after 06 months, I faced a Display problem (blank screen-no display) and I lodged complaint on 16/06/21 against key id no.[protected] but due to some error your support team wrongly closed my complaint, when I enquired from them, they accepted their mistake and agreed to change the display with no charges and they created new key id on 21/06/21, key id no.[protected].
On 24/06/21 engineer from TVS Electronics Ltd, Thane visited our premises, checked and opened our display and he found that CT Number Sticker was not there on the back of our Display which was replaced by Q-Digi Services Ltd, Mumbai in the month of December-20 and engineer from TVSE did not replace the Display, and he gave in written in report that due to non-CT Number he is not changing the display, I am enclosing the image of his letter and image of back side of Display which is shown to us by TVS Electronics Ltd. engineer.
Then again, we contacted HP support system thrice for the same, they told us that finding of the CT number of products is not our folio, and asked us to mail service head for the same problem, and they will provide you the CT Number, and after receiving CT Number we will send our Engineer for replacing the Display. You are requested kindly provide us the Display CT Number.
Waiting for your favorable reply.
Note : above mail sent on 3.7.21 to [protected]@hp.com but no reply received.
Thanking you
