Bad services

Goodday, I am very upset with the service I am receiving from Defy. My ovem is still on warranty. I phoned Defy to come out and fix it. I was told that they would first have to send somebody out to assess. They found a part that was blown plus the oven light. These items were to be ordered and the waiting time was three days. They come out and according to the technician it was repaired. I tried using the oven that same day and it did not work. I then called Defy again and lodged a other complaint. It takes them three days to send a technician out. He arrived today and reported that the timer was broken. Again it has to be ordered (Defy will only open again on Monday). This means that it will then take another three days before they can fix it. Including weekends this is now the third week that I cannot use my oven. I find it unacceptable. My money was good enough when I bought the stove, hob and oven but now the service is terrible. I have a few people coming over for the weekend and how does Defy suggest I serve them food. I will now be posting this e-mail on Hello Peter. Contact me on ***. Ellen Glaus
