Amazon Order Canceled Due to Suspicious Activity

For approximately 15 days, I have been trying to purchase a Stanley-branded thermos through the Amazon Türkiye website and mobile app. However, despite my orders being placed successfully, they are automatically canceled about five minutes later due to what appears to be a system error. I have attempted to place orders at least 15 times at different times, but the same problem occurs every time.

Although the account, credit card, and customer information are all mine, Amazon keeps sending me messages stating that my orders have been canceled due to suspicious activity. When I contacted customer service, I was simply advised to try again after two days. I waited as instructed and placed another order, but the issue remained unresolved, and my order was canceled again.

I am attaching screenshots of Amazon's order cancellation messages and my purchase history as evidence. I intended to buy this thermos as a birthday gift for my daughter and son. Because my orders were repeatedly canceled, I was unable to give them their gifts on their birthdays. When I later tried to order the product again, I discovered that its price had increased significantly. This situation has caused me both financial loss and considerable disappointment.

I request that Amazon address the inconvenience caused by these repeated system errors and offer an appropriate solution regarding my canceled orders and the increased product price. I also ask that the issue be thoroughly investigated and that I receive a clear explanation and a satisfactory resolution.
