Have you tried this location online (via PC/laptop) as below or mobile (via final link within link below)?
Have you plugged in a phone (borrow one from a friend, family, neighbour if you don't own one) and tried ringing out to your mobile to get caller display?
If none of the above works then wait for the forum team to look up your account info. They may take a few days to reply.
