HELP: I can't delete a service provider!!!

Hi,

I came across a bug when I’m trying to delete a service provider. I deleted a user who I selected as a service provider. Then we I got back to the service provider page, it became assigned under my administrator ID, however the ID number shows as the deleted ID number. I tried to delete it from the service provider, by unchecking all services. But it won’t go away! How can I delete it then? Thank you very much!
