Flipkart — Not picking up the product

I have ordered a slipper from flipkart on June 2, 2022, but the wrong product came like other slipper which I have not ordered.. I raised return request, but delivery man refused to take my product, saying that he will only collect the slipper which I have ordered. But how can I give ordered product when wrong product delivered to me!! I have raised the return request again and again, also without asking me the pickup company ekart rejecting my pickup stating "customer decided to keep the product" -- when I told this ekart???? .. So please take action against this. .. Order id is : OD[protected]...
