N11 Lost My Returned Product and Refuses to Provide Any Information

I purchased an international product through N11. Since it was not as I expected, I returned it. The product I sent from Kayseri was delivered to an address in Sivas. The status showed as "Return under review." Later, the seller rejected the return, claiming the product had not reached them. I submitted another request, and the return appears as "in transit," but I have neither the package nor the product, and I have no idea who it was delivered to. Customer service is not providing any answers. I contacted Aras Kargo to get the phone number of the recipient, but the number is no longer in service. Aras Kargo told me that the branch where it was delivered said there was no issue and that it was sent to the address the store had agreed upon. However, if that is the case, why did the store reject the return?

In the return section opened by N11, the shipping status reflects my previous package delivery status. I also contacted World Express, which only imports products from China and does not return items there. So, where is my product? Why is N11 not providing me with any information? If my one-week waiting period expires without resolution, I will file a complaint with the Consumer Arbitration Board. It is unacceptable that such a well-known local sales platform cannot manage a simple return process. Other platforms, like Temu, issue refunds on the same day without even asking for the product back. Unfortunately, our local sales platforms take both our products and our money.
