Myntra sale on 30th oct 2020, i bought shoes at discount. I was charged cost of product + handling fee(98rs).

Myntra cancelled my order and refunding only product amount but not handling fee.

Its ok if i get cheated but how many such customers they are scamming like this and how much free money they are stealing from customers pockets showing promotion and cancelling orders and stealing extra fee they are charging.
