Meesho App - Wrong product recieved

I ordered * products differently from a supplier from the Meesho app. I recieved both the products in same packing on the same day and both the products I recieved were completely wrong products, i immediately initiated a return request, the pickup partner who came to pick the parcel took only one product away and left the other saying that he was directed to pick only one product and that I should again raise a return request this happened thrice, everytime I chatted with the Meesho executive they said the product will be picked up and I'll get my refund after that, but each time the pickup partner came the pickup was cancelled. After contacting the Meesho help centre they refused to refund my money back and kept repeating the same words like a computer bot. They aren't accepting that it's a wrong done on their side, even after their * day easy return policy they are not returning my product and refunding my money.
