Paytm Mobile Solutions — not refunding or replace warranty product

Address:

Dhanbad, Jharkhand, 828205

I had purchased a HP Laptop Bag From Paytm on 31st Aug 2018 sold by Kaasni
Traders(Order No. [protected]).The Bag was under 1 year manufacture warranty mentioned in detail of product in Paytm.
After using roughly 1 week the bag, the stitching part of bag came out (literal meaning get torn ) which comes under warranty condition.
Now when call to Hp service center for warranty as mention in Paytm. One of the Hp executive inform me that Hp does provide any such kind of warranty in Bag.
I had informed about regarding this to Paytm Executive and they first asked me to bring a written proof of "What HP executive said " .
As this was not possible so other solution given by Paytm was that they asked me to contact the seller "Kaasni Traders ".I tried to contact from seller but response came from other side.
Further Paytm asked me to upload the Photo of Bag showing the present condition. I had proceeded as said but in vein reply of Paytm Executive was "The product uploaded was damaged ".
Now i cant understand how can they say that as the product is in warranty and warranty of bag includes any stitching comes out or bag get torn while using properly..etc
Despite of all these the service provide by paytm on resolving the issue is too poor.Almost take 1-2 months but till now not get resolved.
My request is to first of all avoid selling fake product if you cant provide warranty and avoid mentioning wrong details about product.
Second replace my bag or refund the money as warranty proceeds
Hoping for positive response and strict measures to be taken against this fraud, mistreating the customer etc.
Here is some pic i am attaching too for proof.
Thanking You
