1) make sure you are signed out
2) click on my o2 on the right hand side (IMPORTANT click on the my o2 bit not the down arrow next to it)
3) then go to the manage linked accounts bit
when I go to the home page before signing in, I click on My O2 at the top and then there is a link on the right hand side. If I then click on the link it takes me to the sign-in page. When I sign in there it shows all 5 of my accounts.
Hope this helps
