I have rac black box insurance, and I noticed my score went way way down, so I called them. I was told that I wasn't driving enough miles to offset against two acceleration "incidents" (uphill in my little car basically), so I start driving a bit more, then I receive a threatening email telling me to call them immediately to discuss my higher mileage, and that they may need to increase my premium! They told me to drive more, ridiculous service and use of scare tactics! Not to mention when I had an issue pop up, I rang them to tell them it was going to the garage (they have to unplug black box to run diagnostics), I got two emails from them threatening to cancel my insurance if I didn't plug it back in!!!
