We have a brand new home that is outfitted with all Miele appliances in the kitchen. Recently when an accident occurred and the inside glass panel of the oven got broken, I was disappointed to find that the Miele service doesn’t have a basic item like this in stock. Not only do I have to pay >R5000 for one piece of glass; in addition it has to be ordered from Europe causing a 10-14 working day delay. So, I’m without an oven for the next three weeks at least. I truly expected a higher level of service from Miele.
