Vitality Drive speed penalities inaccurate

Vitality Drive regularly incorrectly flags me for speeding. 6 times in the past 5 months. Your speed data is really bad! And when I point your errors the data is not fixed. I am tired of having to email you every time and prove that I am not speeding. How about we reverse the roles and everytime your system thinks I am speeding, one of your staff can manually check google maps for a speed limit signs to prove that I am speeding before you deduct points from me! This system of yours is meant to encourage and reward good driving. This is made pointless when you regularly penalise me even when I am driving well!
