Every time I've called to update details or complain, it's always been stress free. The app works great however, the scoring system confuses me, as I can drive the same as everyday to work and once a week be given an awful score for speed even though it's taken the same time to get to work, so the speed isn't reflective. I did have one day that my box said I did a journey that started at 7:30 and ended at 6, which are the times in leave and get home from work. This journey didn't happen it was parked in the car park all day not being driven. The usage isn't great as after an hour you get the score from the drive to decrease. So if you travel don't get a box.
