We had this problem a month or so ago and the people who answered the Facebook Messenger service were extremely helpful at getting my address registered. I see that the Facebook Messenger service isn't working at the moment due to an upgrade. What a shame since it's the best way to get clear answers for these types of trickier interactions.
Good luck! When you are able to reach a human, I suspect things will be fairly quick to sort.
Hi @Stick73, please private message me the address you'd like, and we'll do further research to see if we can add it. To message me, click my name and click "message"
Hi Stick73. I am just following up on this post you created. Were you taken care of? Let me know if you need further assistance.
