Jeeves Consumer Services — Warranty claim for TV

Address:

Jeeves Consumer Services Private Limited Buildings Alyssa, Begonia & Clover,Embassy Tech Village,Outer Ring Road, Devarabeesanahalli Village, Varthur

I bought a TV from Flipkart on 05/03/2021 and while installing it (provided by Jeeves), an extended warranty for 2 years ending 04/03/2024 was sold to me by a Jeeves technician.
unfortunately, the TV had an issue in the warranty period but now Jeeves is denying to provide a warranty claim stating TV serial no and our policy serial no do not match.
I have question
I have a product invoice from Flipkart
I have the same product which is in that invoice.
the wrong serial number you kept in your record and on that basis how do you deny the claim?
