Hi David,
I understand the importance of getting your issue resolved, however, kindly note that this community is composed of fellow Microsoft users—we are not Microsoft employees and do not have access to check on the case number you provided.
With that said, I suggest to get in touch with live Microsoft Support then provide your escalated case number so you will be endorsed to a live Tier 2 technician who is equipped to handle more complex issue and help resolve the issue.
