Aliexpress Order Cancellation and Refund Issues

I made a purchase on Aliexpress on October 14 at 23:47 for ₺511.28, but canceled it on October 16 at 00:18. Despite an earlier smaller order refunding promptly through Iyzico-Aliexpress, this larger transaction showed as "Aliexpress-London" on my bank statement, and the refund has not appeared. After multiple conversations with both Aliexpress customer service and my bank, no refund has been received. Each customer service representative gives me a different refund time and date, despite providing screenshots of the supposed refund confirmation. Aliexpress keeps offering vague reassurances like "Your money is safe," but they fail to provide concrete evidence, such as a valid receipt or clear transaction proof. This has shaken my trust, and I'm left without a proper solution. I hope this issue is resolved quickly, and my refund is processed without further delay.
