Makro Did It Again

I bought a defy stove online from makro and received it on the 10/08/2018. The front plate on the left stopped working completely in few weeks and Makro sent technicians from defy to replace the plate. The plate worked fine for a week. It now switches off on it's own and switches back on after it has cooled down. In most cases when we turn on the plates there is a smell of wires coming from the stove. I have been calling Makro since from October and they take me from pillar to post. I even sent an email to an email address I got from the consultant who told me that I can't speak to a supervisor or a manager as they were all in a meeting, I still have not had any response. I wrote on their facebook page twice asking for assistance andthey keep on promising that someone they'll get soomeone to call me and no one has even attempted to call me. All I need is this stove to be replaced. Order number MAK924978.
