I'm a freelance worker and I needed to hand over my Issuu account (which I ran on behalf of my client) so the client could run the account direct. I couldn't find a way to remove my billing information (e.g. credit card) ahead of handing over.Alex from Support was really helpful and very speedily sorted this out for me. I really appreciate how quickly he resolved this, and for his clear and positive action. Thanks Alex, and Issuu!
