Karcher Bad Service, Weak Machines

Bought a pricey SE4001 almost R5k less than a year ago. Took it for repairs at Kärcher's new head office (Boksburg) a month ago (early Dec), no call or any form of feedback from the lady for 4 weeks. I drive 25km there again to enquire on 3rd Jan, 1st thing she says is that there are no technicians, they return on the 9th Jan, hence the delay in feedback, was told to return on the 9th. I insisted for confirmation that she even has me and my machine on their database, she found my details, found my machine and a R2,600 quote miraculously,motor fault. How, if there hasn't been technicians to diagnose the issue? Asked about a warranty on this expensive machine, told that doesn't exist as it's a motor, after 7 days I'm on my own. Told to buy another new expensive machine for R3600 and turn in mine (new condition also). Why am I paying R3600 after few months of owning a machine I bought under the impression it was quality and the establishment is reputable and fair? Basically told to pay or take my machine, took it and now have an expensive yellow thing reminding me how terrible Kärcher's service is. Absolutely terrible and costly experience.
