Awful customer service. I’ve had a black box policy for 2 weeks and all my scores are excellent (100% or minimum 90%) but the acceleration varies between 0% (very poor) and 25% poor. At the start it was good but now is at the lowest point it can be. I have not changed the way I drive. I am a 42 year old mother, usually travelling with my child in the car so am super careful. I don’t speed (my speed score is 100%) so how can my acceleration be so poor? I think the box is faulty, no matter how I drive (I’ve experimented accelerating fast and accelerating gently and acceleration super slowly and the score does not really improve). I think this is a way to get money out of me by increasing my monthly premiums. I’m so annoyed with this company as no one answers the phone or replies to any live chats or emails. Seems I’m not the only person who has experienced the same issue with the same company. AVOID!
