Defy appliance - gone to the dogs!

I bought a new washing machine from Defy in June 2020. To date, I am unable to use the machine as it came with factory faults. Three technicians, namely Mandla, Ringo [came twice] and a Senior technician, Roger came and checked the machine and found it to be faulty. I was then told that a new machine will be given to me but to date this has not materialised. Many parts were ordered for this machine including the top cover, etc which I think was not faulty. How can a new machine come with so many faults??? I believe, there is something sinister that is going on! I made more than twenty calls to Defy and all I get is empty promises. This morning, 10 Sept., I waited for over 20 minutes [around 10:25] on the line and nobody answered the call, not even the receptionist. It looks like Defy, which was a reputable company has now gone to the dogs. Can you imagine that my wife makes a comment "the machine is only for show" . She could have got one from the s**** yard if she needed a show piece. This is frustrating with such poor service and non delivery and workable machine for over 3 months now.
