Levi's India — defective jeans

Address:

BTM, 560076

Bought a few pairs of levi's... I didn't use them for more than 5 months... However, once i did, i noticed there was a defect in the stitching. I took it back to the store in vega city mall. They gave me the run around for over 2 months... Saying it was a ironing issue and nothing more
Kept informing them that the stitching is wrong, and this was once confirmed by their own tailor, but the manager, who seems more like a goon than a manager refused to budge... Further delaying the process and only making me run around.
Eventually once they had to replace the jeans, he said it's been too long and they would not do it. He blatantly refused and said if i have any issue speak to the customer service team.
The worst manager and store... No knowledge with anyone and they don't care one bit.
7 years ago i had a similar issue with my 501's
.. I thought nothing would be done, but at that time the site in garuda said levi's have a lifetime warranty and replaced those jeans even though they were a year old. That is customer service.
Hope someone gets in touch with me and helps me with this issue.
Thank you
