PlayStation Call of Duty Modern Warfare 2 Purchase Return Issue

attempting to purchase Call of Duty: Modern Warfare 3, due to a system error, I unintentionally bought Modern Warfare 2, a product I did not want. The combined cost of both games is 1999 TL, creating confusion and dissatisfaction. To initiate a refund, I was advised not to download the game, but the approval screen showed Modern Warfare 3 after the purchase. I proceeded with the download, only to discover upon entering the download section that I had received Modern Warfare 2 instead. This has left me in an awkward position, as my money has seemingly gone to waste. I do not wish to acquire Modern Warfare 2 and seek a resolution for my predicament. I desire the third installment of the game that I initially intended to purchase. I am requesting assistance in rectifying this matter promptly. The transaction number for the purchased product is 500024135085. I hope for a swift and satisfactory resolution to this issue.
