Big Eazy nightmare!

I bought a motorcycle (2008 Yamaha TDM 850) cash from this dealer. Firstly when I bought this motorcycle for my son there was a problem with the thermoswitch which did not kick in. The owner Johann Claasen then promised to get a new replacement part. He then bought an incorrect part which did not fit on this motorcycle. At this stage my son was working in Johann's workshop and the current workshop manager suggested that they put a switch on the thermoswitch to switch it on and off manually. This worked well for a while, but after driving this motorcycle for 51km the motorcycle completely lost power and oil came out of the sides of the engine. Now Big Eazy refuses to take responsibility for advise given by their workshop manager. Also it was promised that the motorcycle will get a full service before we take delivery of the motorcycle which never happened. Another concern is that Johann appointed my son with lots of promises to send him for the proper qualifications to assist in the workshop. This never happened and my son had to work on clients motorcycles with very limited knowledge. Johann refused him to do the service on the motorcycle that was promised to me when I bought this motorcycle, this is why I know for sure this motorcycle was never serviced. My son was not the only person working in that workshop with lots of promises for the correct training and qualifications, actually most of them were not qualified to work on motorcycles. It also took them 3 weeks to do the change of ownership and we are still waiting for the paperwork to be delivered to us. Do yourself a favor and stay far away, as this company is full of promises and never delivers.
