changing details

it was very easy to update my university alumini details and my telly tax details online, credit to them for their customers service, however i've been stuck on hold with my car insurance company, edit, now connected and they're having trouble with changing my details, so i'm on hold again, i suspect i'll have to send them a letter and my c-o-n deed in the post to them.
edit, after being put on hold they came back and said they were having difficulty changing my detals but finally got them sorted out, and they'll send out new policy documents to me in the post with my new name on them.
