Do not touch them - con artists !! My 18 had a blow k box fitted. If they get 3 alerts there is supposed to be a review but it did t happen and Sterling just cancelled his policy. We had no details at this point about what he had supposed even done to warrant the cancellation (black box dept don’t automatically supply details of speed being undertaken where). Has left my 18 year old with a marker for a cancelled insurance. It’s been a week since this happened and no one has even called me back even though I said I wanted to complain. Now offered new insurance for twice the price. I’ve got an alternative quote from Admiral that is not twice and no black box. A blatant attempt to cancel on an 18 year old who wasn’t even driving that fast just to double his premium. Current quote from Sterling £4.5k on an £800 car !! Will be taking to Financial Services ombudsman.
