bad service and added charges when servicing vehicle

Created a Facebook account just to give an overview of the experience that KTM Trax gave me. great service when buying a motorcycle from them. unacceptable customer service when booking in your pride and joy to get serviced, after confirming a quote and asking to be called for any additional charges due to past experiences, then getting charged a whole different amount. After *****ing the amount from the till point, being told to pay and speak to the workshop. additional items used without notification from the mechanic.
