Hi Josh -- Drew here -- our escalations team should be reaching out shortly. (Losing phone, 2FA keys, etc. can be tricky but they should be able to work with you and hopefully verify enough to get you unblocked.)
Coincidentially, I know the new CEO, Ashraf Alkarmi; we met at AWS when he was launching Appstream, I believe back in 2013 if I'm not mistaken. It's funny to recognize a name. I am hopeful that he will do well as a CEO.
