My son has been insured with RAC black box for the past 9 months, recently his circumstances have changed due to work resulting in him driving more miles and therefore initially added a further 2000 miles to his policy. More recently, he firstly received an email informing him that his mileage will be automatically increased, followed by a second email stating his policy will be terminated. Speaking to RAC, they informed him that the underwriters we're not willing to insure him for over 10,000 miles, this I would understand if he had a poor black box record, however, his record is excellent and taking into account they had previously increased his milage we were left frustrated to say the least that RAC we're no longer willing to insure him. Maybe I've missed something, please show me in legislation where a young driver is only permitted to drive 10,000 miles because I'm struggling to find it! RAC did offer an alternative underwriter at a cost of approx. 2K, unrealistic and quite frankly insulting, there seems to be a desire to drain the youth of as much money as feasibly possible, almost preventing the young man getting to work! He is now moving his insurance, unfortunately at an increased cost, he was three months away from earning his first year of no claims, however, RAC have taken that away from him at our expense. I am disgusted that you also have the audacity to charge him £125 to cancel his policy, what exactly do we get for £125? I'm really struggling to understand what would warrant this expense and I doubt we are getting value for money, unless of course you can demonstrate that it takes one of your employees an entire day to cancel policies! RAC has wasted his opportunity to build up his no claims by failing to account and accommodate peoples changes in circumstances, you should be ashamed of your rather poor service given the incredible cost in the first instance.
