DEFY APPLIANCES CUSTOMER SERVICE -non existing

I have had someone out to look at our dishwasher, they told me it would be 24-72 hours to get the part. This was on the 4th of FEB. I went to the cape town office on the 3rd of March as the guy never bothered to call us back or let us know if the part was received or not? I then asked to make an appointment for today, Fri 06/03/2015 @ 4pm. Robin said the guy would call me the next morning (Thursday 05/03/2015. I then called for the service manager in the afternoon on the 5th and he too has not called me back. I am sick and tired after running after your service department to come and repair your machine. This is not the good service your company pretend to have. This is pathetic. I'm prepared to even get a refund and purchase a different brand. This is not the first time your \ service guy"has not pitched or came for an appointment. I request you come out and fix the DEFY and reprimand or get a new person to service your clients.
