Myntra.com — Refusal of exchange, fraud

Hi, I placed an order of black ballerinas Flats on myntra on October 2020 the company brand name solehead but Instead I recieved a Chapal with the same brand, I clicked the picture of the shoes and package and everything that they asked me. I spoke to customer agent on the very day as well. I was asked to send the image on their support mail which I did and I was told it would be exchange. After several days of delayed of exchange I called their customer service and now they said my exchange request was rejected. I have every proof, even phone call conversation.
