Worst after-sale service for repairs.

Worst after-sale service, my stove is still under warranty and the plates stopped working, I logged the callout service request via the website. A day later I got a call that the technician will be onsite within a week. It'ss now more than a week and every day I must call and ask when the technician will come out as I cannot use the stove. And every time I get the excuse that they cannot get hold of the technician. I actually after many calls and wasted airtime, I got a job no to track ***. And every time I call the Cape Town warehouse it sounds like they do not know what they are doing. I then end up calling the national number to get the same excuse that they cannot get hold of the technician. No one will call and advise what the hold-up is.

Please can someone get the technician out to fix my stove?
