De’Longhi Magnifica Plus – Touchscreen Malfunction

I purchased a De’Longhi Magnifica Plus coffee machine from the MediaMarkt store in İzmir İstinyePark on 8 December 2024. Shortly after the purchase, the machine started making an unusual buzzing noise. I contacted the authorized service, sent them a video showing the problem and requested a replacement, but instead of changing the product they only carried out a repair and returned the same machine to me. In the last 7–10 days, a new problem has emerged. The touchscreen has started to malfunction by randomly selecting options, navigating through the menus on its own and even turning the machine off by itself. This situation makes it almost impossible to use the machine as intended and is very frustrating. Having experienced two serious malfunctions in such a short period of time, I have completely lost my confidence in this product. Unfortunately, neither MediaMarkt nor De’Longhi has provided a satisfactory and permanent solution despite my previous application. I expect De’Longhi to stand behind its product and I formally request either a brand-new replacement of my coffee machine or a full refund of the purchase price. I kindly ask for my complaint to be evaluated urgently and for a clear, satisfactory solution to be provided as soon as possible.
