Can’t verify security Info, thus no access to change account details.

I was forced to update my backup email address which took a month to do, and now I can't verify that email address or change my account info. It keeps telling me it's sent a code to the back up email address, but I haven't received any emails from microsoft in my inbox or junk folder. It's put asterisks in my email when it displays it, so I can't even see if I've just misspelled the email address.
