Just the worst experience, extending for a whole year. Can't go into detail here because the issue is complex involving bereavement, a property with energy bills I have inherited and a spectacular lack of communication between SP departments. It's just impossible to get any sense out of anyone to resolve an ongoing problem. Everyone on the end of the phone is polite and helps the best they can but they are held to a script and set of procedures and are unable to help in any real terms. Oh, here's another trick. One department promises to put you through to another and then the phone goes dead! Really nice.
