MAKRO WONDERBOOM - BOSCH SILVER DISHWASHER

I have been trying to get assistance from Mako Wonderboom for over a week. I reported that my BOSCH Dishwasher does not run the full circle and wanted them to come and look at it as it is still under warranty. My first phone call was on 21 May 2019 from which I received my reference number (91248). I called back on Friday (24 May 2019) to enquire about the repair of the dishwasher and was told that they will call me on Monday to arrange a time for the repairer to come out and look. On Monday afternoon (27 May 2019) I phoned again, and was told that Bulelani was busy with another call and he will call me back. Tuesday, still no response and phoned again and was told that he was busy and will phone me back. Three hours later and I am still waiting for him to call back. This is not acceptable. Have never received such bad customer care before.
