Metro Shoes — skechers walking shoes

Address:

Jaipur, Rajasthan, 302003

I purchased skechers shoes 3 months back, within 3 months inner lining & foam near ankle started wearing out leaving a hole, along with stiching done on front of shoe is loosend.
I lodged complaint for this in store in gt mall jaipur, sales persons were convinced it to be a genuine complained & assured me of all help.
After 1 month i received mail for complain no s01022018d5 stating that this is a routine waer & tear so complaint is declined.
If such a costly shoe wears down in 3-4 months where should a consumer go?
In fact skechers india is selling chinese made product with substandard material in name of world fame skechers.
