They denied to return or refund for damage trouser...

They denied to return or refund for damage trouser, insisted replacement only. They sale used, repaired/restored cloths as shop person himself told that trouser was re-stitched. Bought a shirt & trouser on 28.4.18 with inv# 1776. Stitches failed within 4 hours use on 9.5.18 on my anniversary.
This is not a professional & fair practise
