When i received a parcel from myntra then I open but found blouse instead of Peter England men trousers

I had ordered an item from Myntra. When I received the parcel and opened it, I found that the product inside was not the same as the one I had actually ordered. I raised this complaint with Myntra, stating that the product delivered does not match what I had purchased. However, Myntra has responded saying that they delivered the correct product and that they cannot issue a refund. I request Myntra to either replace the item with the correct product that I had originally ordered, or refund the amount paid.
