Myntra.com — Product replacement scam

I ordered Order ID # 1316884 [protected] and paid ₹2582 but I replaced the item with Order ID # 1316987 [protected] to my surprise they have delivered both items together and the delivery guy was asking for money for the new item. So I cancelled two items eventhough tommorow i ve a jury for that really need it.I tried calling the customer care, but they are not at all responding.Atleast gibe me the money back or replace the item correctly. If myntra cannot offer such things please remove the option from the app.
