DEFY STOVE HOBB NOT WORKING AND DEFY HAS NOT ATTEMPTED TO ASSIST WITH TECHNICIAN

I purchased a Defy stove hobb at House and Home Pavillion, Durban and after 11 months the stove started pressing itself in the early hours of the morning as I was cooking. After numerous attempts by myself and House and Home to log a complaint with Defy so a technician could come assess my stove. Defy has not attempted to reach me even once, when I contacted Defy they told me about a three day turnaround time, and they have still not contacted me or even sent a technician a two weeks later!!
