Beko Toaster Warranty Issues and Unfair Service Charges

I bought a Beko-brand toaster, and it broke down just one week before the warranty expired. I contacted customer service, and they sent me a link to schedule an appointment. I scheduled an online meeting for September 30, 2023. However, no technician arrived on the scheduled date, and when I called, they claimed I had not scheduled an appointment. I rescheduled the appointment, but they still did not show up. After they canceled my appointment on the third attempt, I contacted the headquarters. Finally, the service team arrived at my house. To my surprise, they insisted on charging me for the service despite the fact that the broken button on my still-under-warranty product was not covered. They gave absurd explanations about electricity without ever measuring anything in my house. How can a device that has only been used 48 times in two years fail so quickly, with no user error? I believe that this situation is malicious, and I demand that my complaint be addressed. If not, I want to make it clear that as a consumer, I will vigorously defend my rights.
