Have you tried your EA/Origin password just in case, if the accounts are linked it is possible for that password to take precedence
also try a password reset at this link and see if that solves the issue
The only other thing i can think of is the account is banned from the servers .....
If the above fails it is best to phone the accounts CS
see db woodynz post here with a link to numbers and how to use skype if you have it.
Using skype with that contact is a free call to the best of my knowledge, that number is only available as per the hours listed (Support available from 9.00 CT - 21.00 CT) so need to confirm time zone etc
