Amazon Canceled My Order, Increased the Price Astronomically

Whenever I purchase a product from this company, they either delay the shipment or cancel my order altogether. I bought a product for 25 TL, and they canceled it overnight. The next morning, they increased the price of the same product to 1399 TL. What kind of price increase is this? It's frustrating to have such issues every time I shop from your company. Moreover, I have to wait for a whole month to get a refund. I don't want a refund; the product is currently in stock. What I want is for my products to be shipped to me as soon as possible.
