Amazon Seller, Faulty Cosori Airfryer, and Unresolved Refund

On March 13, 2023, I purchased a Cosori Airfryer directly from Amazon.com.tr. Mold began to grow on the Airfryer after about three months. I contacted customer service and asked them to send it in for warranty service. Surprisingly, they informed me that there is no service center in Turkey and that the only options are replacement or refund. I requested a replacement first, followed by a refund, which they accepted. I securely packed the item and sent it via MNG Kargo using the provided code. After some time had passed, I inquired about the refund status. Customer service assured me that the item had arrived at their warehouse and that the refund was in the works. However, they later revealed that the product was rejected due to alleged warehouse damage. They suggested that I ask Cosori for a DOA (Dead on Arrival) certificate and resend it. This is a frustrating situation because I sent the product in good condition. Furthermore, the two-year warranty appears to be meaningless in the absence of local service. I filed a complaint with the Consumer Rights Arbitration and demanded a refund right away. If necessary, I am willing to go to court. Amazon, stand behind your products or arrange for proper servicing!
