Levis — Uncomfortable wear due to rough threads in jeans

Address:

122001

Purchased a Black Jeans from Levis store (Saket, NCR) in Jul.
There are design patterns of thread in Jeans which is hard and rough to wear.
I raised the concern while purchasing but the vendor at the store told that the threads will get softer after a wash and will not create issues.

When I wore that for long hours(office hours), it make patches and rashes in my legs. whole day was a uncomfortable day for me due to that jeans.

I want a solution for it otherwise I would like to adjust my money to some other model which is comfortable to wear.

Thanks to reply.
