Poor After sales/repairs

End of September our Defy box freezer which is still under warranty broke down and we logged a service call. The technician who lives close by visited us a week later and said he must order parts and left. He only fixed the freezer three weeks later. It is now a month later and the freezer is out of order again. We logged a service call on 20 November 2017 and they promised to schedule a appointment soon. Today is 25 November 2017 and no appointment has been scheduled. This company do not care about their customers and it seems their products are inferior.
