It really is a shame that you had to be treated this way. Cars and technology are evolving at breakneck speed these days and to keep up with it all is a dizzying spectre. This, coupled with the wealth of information available to us all on the Internet sometimes makes the customer more savvy than the repair facility in certain respects. Service personnel need to be open minded about these facts and listen to their customers rather than take the position that they know everything and the customer knows nothing. It is a learning experience for both parties. We as dealers have access to some proprietary information regarding the products that is not readily available to the general public. That information should be utilized to verify customer's concerns rather than to refute them, and if necessary, to dispel myths that often crop up in many of these forums so that problems can be readily resolved. There's no room for egos in this business. Hopefully you will find someone at your dealership who will empathize rather than chastise.
