SCAM. Similar experience to many reviews on here. My daughters insurance cancelled after 2 months as black box indicated bad driving. This after she had already had a years insurance with same black box (different insurance company) and driving record was exceptional. Even had our friend who is a driving instructor take my daughter out and confirmed her driving was fine. £210 charge/fine for cancellation. Lodged formal complaint with the company but don't expect any satisfying result. Don't want to let them keep getting away with this as clearly taking advantage of young drivers. SCAM!
