Defy service deplorable!

We purchased a defy glass hobb in October 2021. It has four electric plates and 1 gas burner plate. It worked beautifully energy efficient. On 17 April 2022, almost 7 months later, the glass top spontaneously cracked. We reported this to major where we purchased the hobb from, major informed us that a defy technician will assess the damage. The defy technician came to our home and aside from being nonchalant about the situation made a point to tell us defy will respond when they decide too-he can’t give us turnaround time. We went back to major a week later and major informed us that defy will replace the part and will call us. Now R6000 spent on this, almost a month later no response. I have no stove to make food for my family, the inconvenience is unacceptable because my children can’t live off cold sandwiches any longer. Defy appliances are usually durable and reliable but this service is deplorable with a ‘don’t give a damn’ attitude towards us. Very disappointing especially since we were loyal to the defy brand for over 15 years.
