Poor after sales service, MAC Africa chain saw

A few years ago I bought a mac africa electric chain saw from Adendorff in Boksburg. Recently the cover on the chain adjuster broke. I called the Edenvale branch and the consultant insisted I brought the machine so he could see what part I am looking for. Upon arrival he said they don't stock the cover and will have send my machine to headoffice which I was reluctant to do knowing my machine would be gone for a couple days. I sent the machine to headoffice and thats when the trouble started. A week later .they could not find my machine, I was reffered to one person after the other. I eventually ended up speaking to a Keith at the headoffice in aeroton JHB. He managed to find my machine and after a long conversation advised me that they don't have the part. He tried to sell me a newer model instead. The long of the short is he told me that my machine has been discontinued and parts are no longer available. I insisted my machine be sent back to Edenvale branch so I can collect it, after another week I was told my machine was sent somewhere else for repairs. When I contacted Keith again, he became defensive and arrogant, I insisted on speaking to his manager Ockert who inturn very nicely told me that I have to buy a new machine. The moral of the story is, Adendorff sells their own brand mac africa but cant supply spares. I never advise anyone to buy anything from Adendorff especially mac africa products since their support is terrible base on my own experience. Its almost a month later and I still don't have my machine back.
