Terrible service centre

My washing machine broke sometime in March. I logged a repair through the retailer, Makro. The technician responsible then showed up to my place unannounced while I was at work so I had to postpone. However nobody followed up with me. Fast forward to June,machine is still broke. I log another call. This time I'm given a date,10 July. This date comes and goes and I have to call them back again to find out when they are coming to fix the machine. Eventually they check it out. I'm told it needs a new part. 3 weeks later I have received no communication as to when I can expect the part to arrive or if there were delays. Completely disappointing service.
