Pepperfry — Defective recliner under warranty is not replaced as vendor is denying

The single seater sofa recliner was bought from pepperfry in July2022 with a 2 year warranty.
1. The stitches came off from the right arm in the month of May 2023 within a year and a complaint was filed with Pepperfry.
2. The vendor picked up the product and while fixing the stitch in the right arm damaged the fabric at another place and just simply stitched it up which looks very evident. This was raised with Pepperfry immediately and I got an approval from the customer care that a replacement will be provided as this was damaged by the vendor.
3. Then pepperfry went back on their word and said the vendor is denying replacement and we can't do anything. I'm not sure how a vendor can deny replacement for irreparable damage that the vendor did in the first place for a product under warranty.
4. The vendor then again picked up the product and fixed the stitch alone and returned the product with his damage still not resolved. The stitch that was fixed also came off again in a couple of days.
5. I consulted with another third party sofa technician, and he confirmed that the fabric is defective and the only solution for this is to change the entire fabric.
6. The vendor is neither accepting to replace the product nor replace the defective fabric and asking me to pay for the repair work for a product that is still under warranty. Pepperfry is also denying replacement citing that the vendor is denying the request.
7. This has been going on for more than 4 months now and now the stitches have started coming off at other places as well as the place where the vendor fixed it a few weeks back. Now the recliner is absolutely not usable.
8. The latest case registered with pepperfry is EM[protected]
This has caused me so much mental trauma and I've been talking to the vendor and pepperfry for at least 15-20 times a week. I want Pepperfry to replace the defective product as it is still under warranty or provide a full refund of the product and compensation damages for my mental trauma.
