Virginmedia/O2 Sign in issues

Having issues logging into this new fangled joint login system. Get so far but the verification email never arrives. Tried creating new account with differant email and linking vm / o2 accounts to that but still have same problem as it needs to verify im who i say i am by send link to existing email, said link never arrives. Its a vicious circle. Tried clearing cache checking junk folders but no joy. HELP.
