Defy service centre Parow ref***

Faulty stove reported by Game and myself to Defy on 27/06, to date the stove is still not attended to. I’ve left countless messages for the service manager Christopher, he has not returned any of my messages because he spends his time in meetings. They have attempted repairs in this stove 3 times before by replacing a computer box (symptom), but the problem persist with no permanent solution. I have now emailed the GM who I hope will address my concerns. Wishful thinking
