20-aug customer email reaching out to customer care for update unable to reach [protected] or[protected] for update.
As there is no update from the kurlon.

24-aug customer phone i was informed that stitching issues should be reported within 15 days of the product bought, it is mentioned in the warranty card
(I haven't got warranty card, when i bought the product from kurlon outlet)
Even that doesn't sound right as the product is covered on the warranty and stitching issues should be also covered as it is standard out of box product there is no additional customization which customer has added

I have attached the email chains, from the above chain of events. There is one follow up from kurlon asking for the product pics and invoice which was shared 15 days back. I am planning to take up a legal route as there is no update on the email chains for the last one month.
