I would like to cancel my insurance policy, which is with Diamond. On the back of my certificate of motor insurance it says there is an admin fee of £45 for all cancellations, I fthink this is a really high amount! What should I do? Should I write to them saying I will not pay the admin fee until they post me a breakdown, should I just pay the total amount, and also if I cancel my policy (Iam fully comp) will my car still be insured to me as thirs party fire and theft until the end of the policy term? I would appreciate advise on this!
