Myntra.com — received a damaged trousers

Address:

Bellandur, Bangalore, Karnataka, 812001

I have ordered a trouser (Highlander men olive green trouser) in this sale.
Quality wise the trouser is so good. But there is a defect. On the right leg side there is a hole in it.

Now as a solution myntra is taking the product return & they will refund the only product amount.
They are not returning tax amount, delivery charge.
Even though this is there issue
