Bosch KGN56 Refrigerator Still Freezing Food After Three Repair Attempts

I own a Bosch KGN56 refrigerator and for the last 4 months I have been experiencing a serious malfunction. The refrigerator freezes food on all shelves as if it were a deep freezer, making it impossible to use it properly for daily storage. During this period I contacted Bosch service several times and a total of three repair attempts were made. Despite these interventions, the problem has never been resolved and the refrigerator continues to freeze everything on every shelf. Because of this, many of my meals, fruits and vegetables have been spoiled and thrown away, and I have not been able to store my daughter’s medicines safely in the refrigerator. I had purchased an additional 5‑year warranty for this product, but unfortunately this warranty has not provided any real help and my problem has still not been solved. The whole summer has passed and I am still facing the same malfunction. Because the malfunction persists despite repeated repairs, I have lost confidence that it can be definitively fixed. I therefore request that my Bosch KGN56 refrigerator be replaced with a new, fault‑free product and that the necessary procedures for this change be initiated as soon as possible.
