Incorrect logging of speed and location

Traveling from Sherwood Port Elizabeth to Greenbushes Industrial Port Elizabeth, I was logged doing 170kph on a stretch of road only 300mtr long, plus then travelled 25km in less than a minute even though I was no where near those areas. Even then looking at the playback on Trackers website, it showed me in a shopping centre parking area doing those speeds????<br> <br> Very very unimpressed as it was a company vehicle and the Director gave me a warning due to this. I have approached him and showed him the areas and proof on Trackers website and he also can not explain......before I forget, those speeds shown were, according to Tracker, was done while my ignition was OFF??<br> <br> My Gamin GPS also has no recorded speeds any where near those mentioned.
