I Experienced Significant Inconvenience Because Amazon Arbitrarily Canceled My Order

The product I purchased with Prime delivery from Amazon.com.tr was canceled by Amazon four days after the order was placed without any notification or apology. The payment was simply refunded to my card. I was planning to buy this product from another site over the weekend at a reasonable price, but I decided to purchase it from Amazon instead, trusting in the company's reliability. Now, not only has my order been canceled, wasting my time, but the price on the other site has significantly increased. Amazon is responsible for this loss. I request that the product be sent to me at the same promotional price. If this is not resolved, I will not renew my Prime membership and will suspend my Amazon shopping. I have noticed that Amazon, which used to be very sensitive to such issues, is becoming increasingly indifferent.
