Myntra.com — Product delivered is wrong and myntra is not returning the money

I had placed an order with myntra on 22 May 2024 for a co ord set from Brand "INDO ERA" and it was delivered to me. We cannot open the package until we take the delivery. Once i paid and took the package from the delivery boy and opened it i noticed that the product delivered is from brand "RUNWAY DREAMS". I filed a return complaint for the same as the product delivered was not of the brand I had ordered and the fabric mentioned while placing the order was SATIN but the fabric received was POLYESTER. I have been trying to contact the customer care but they are not helping. I have placed return pick up requests twice but the delivery agent is not coming. If the product delivered by myntra is not what i ordered then they are due to refund me the amount. I have wasted my time calling them but they are not willing to respond. I have attached all details and pictures for your reference.
