I just thought I'd let everyone know that I've been very unhappy with ND's response to the swap over to the M3.
Firstly they refused to insure it under any circumstances which is laughable given my more than insurance friendly profile.
Then, they have said I will get back less than half of the premium I paid for the Coop back in June, despite me using less than a quarter of the policy.
Now, to add insult to injury they are not prepared to provide a refund until up to 6 weeks after the policy was cancelled.
Very unhappy with this service, and I'd advise anyone considering ND to ask some probing questions about possible implications of swapping cars after the policy has started.
