Meesho — Wrong Product received but refund is rejected

Hello,
I placed an order in Meesho - Order ID[protected] and AWB number E[protected]DT ; AWB mentioned in the label [protected].
However, I received wrong Product. I paid COD amount Rs.909 via UPI to the delivery agent. However the delivery status wasn't updated in the app and and so I am unable to place return request.
The customer support rejected my return/refund request and denied that they sent the product. I just want my money back.
