Beko Hood Installation Damaged My Wall and Stove and Service Refuses to Compensate

I purchased a hood from Beko to replace my old extractor. However, the lack of knowledge and materials from the technician who came for installation caused significant problems. He installed it without taking measurements and weakened my wall. He didn't even bring basic materials like anchors and screwdrivers. The technician made 12 holes in the wall during installation, which compromised its structure. After he awkwardly installed the hood, I informed him that it was uneven, but he simply said, "Be thankful it's this much," and left. Since I had a busy day, I started using the hood. However, on the morning of September 27, 2024, the hood fell off the wall and crashed onto my glass stove. I immediately called the service and requested compensation for my damages. When the same technician returned, he said, "Glass stoves are expensive; good thing it didn't break," even though my stove was scratched from the fall. I showed him the damage on the stove and the wall and requested compensation for these damages. However, the technician claimed he had nothing to do with the installation and was only a maintenance technician. I insisted on having my damages addressed and the hood reinstalled properly. He tried to dismiss the situation by saying, "This wall is rotten!" I explained that I had heavy kitchen cabinets on that wall. He produced excuses like, "Maybe it’s mounted on a board behind it." I proved my point by showing him the installation holes. Eventually, he said, "I can rehang it here, but it will come off again. There's nothing I can do, and I'll do that for free," and then went outside. I asked why he would leave without testing the hood, and he tested it, saying, "Okay, this works." I lost time and suffered financial damage due to Beko service's incompetence and technical shortcomings. I have to carry out my daily tasks without my hood, and my wall is in an unusable condition. My stove was damaged. Beko officials need to repair my damaged wall and compensate for the stove damage. I submitted my complaint, but the case was rejected and closed without any notification. When I inquired about the reason, I learned that the service report was completely false. Beko's service provides random hole drilling and uses inappropriate anchors. The cause of the hood falling is entirely their fault. This hood could have fallen on us while cooking during fire-risk tasks.The service team and Beko officials constantly shift their faults onto the customer.
