Flipkart — Warranty Mismatch

Hi,
I have brought new HP laptop- HP 15s Intel Core i5 12th Gen - (8 GB/512 GB SSD/Windows 11 Home) 15sfq5111TU Thin and Light Laptop from Flipkart.

The product shipped on 2dec and delivered at 7th dec, When i open the product build is not good and keyboard are look like already used and check the warranty status show's as activated sep 26. Three months before it's activated and for the same i created the ticket with HP and they said Health & Happiness Private Limited is not authorized service partner of HP, And they ask me to reach flipkart.
