Was fine to begin with. The Black box was fitted promptly and emails with any queries were answered within 1-2 days. However, as time went on, nearer the end of the first quarter, I started noticing inaccurate readings. I was scored -10 for speed when driving within the speed limit. I went for a 10 minute drive locally, when I got home, my driving score for that particular journey was 10/10. When checking before bed it had gone down and said that I went for a 4 AND A HALF HOUR JOURNEY!!! I was in my house the whole entire time. I emailed for this to be resolved, no reply. I then noticed the next day, my driving score was 7, this then went down to 5 somehow. When looking at this I then noticed that I had been scored a -7 for speed and 4 for usage for a journey I DIDN'T EVEN MAKE. I think this is ridiculous. How am I supposed to trust any of the other scores? If I was driving badly, this insurance company would be quick enough to take my money and cancel my policy. Because they are the ones who are liable for this, they refuse to answer me or resolve the problem even when I have emailed twice. I REFUSE TO RENEW MY POLICY WHEN IT FINISHES.
