Myntra.com — shipping charges deducted even after returning the order

Address:	Bangalore, Karnataka, 560068
Website:	Mantra.com

My wife purchased a product from online mantra app. At ₹1014
The product was returned the very next day due to size issue.
However, i was refunded lesser amount i. E ₹865 and ₹149 was deducted as shipping charges.
No other site has this type of peculiar policy that despite return the product u still pay ₹149 net.

Also, mantra often charges gst over discount whereas gst is always included in mrp and during discounting it is already included, but mantra charges extra amount and fool the people.

Neither amazon does it nor in physical store or showroom, extra gst is added on discount.

Mantra in a way fools it's customers...
