Most expensive cement mixer you'll ever buy

I purchased a concrete mixer from Adendorff for R6500. They informed me it had a 1 year guarentee. Less than 4 months later the motor packed up. After taking it back I was told the motor is not included in the gaurentee and it was because I used the wrong extension cord (Id used the 5m extension cord which I purchased from THEM). I was forced to fork out R1350 for the repairs but they assured me the motor was now under gaurentee for 1 year. 2 weeks later the motor packed up again and I was told I needed to pay AGAIN. The cherry in the top: they charged me R1750 for the same repair. What a bunch of ***.
