[Resolved]  Koovs.com / Marble E-Retail — Wrong product sent in place of what was originally ordered and charged for the original product

I had placed an order on 27th july on KOOVS mobile application in which I had ordered 3 items, one of the items has been wrongly sent in place of another product that was originally ordered. They wrongly sent me a denim shorts in place of a denim jacket that I had originally placed an order for. It was a prepaid order for which I paid the price of the original product (jacket) but when I recieved the package there was the wrong item. On the application they said that "Return/Exchange is not available for this item" so I contacted the customer care via email (their customer care phone services are temporarily closed). I have sent them 3 emails along with reference photographs of the wrong products demanding the return of the wrong product and refund for the price they charged for the original product, but still they have not taken any action.
