I complained to Microsoft sales, who apparently escalated it as my request was to defer my automatic renewal until this issue is resolved. They told me 48 hours. It's been 96 hours and I haven't heard from anyone.

I did hear back from some of my in-app feedback submissions, but it is frankly a BS canned response. Honestly if a human clicked a button to respond with this, they should be fired because their job is useless. And if a machine just responded, I'm flabbergasted as to why it took so long for the machine to send such a useless canned response:
