Hi, I have the same problem since Thursday. have been in touch with Text help 07533051809 and moved around "To the right team" several times and keep getting asked if I am the account holder. Afer a full day of messages Friday it just went quiet. I have an old NTL world email but a current VM package and have no problem until Thursday, my wifes NTL worl email still works. I can log onto VM but clicking on email I get "Mailbox unavailable try again in one hour".
