How to remove an unknown tenant?

Jeff Hare 5 Reputation points

My Azure account and applications are not affiliated with a company, just my own. I somehow managed to get an active directory attached to my login that shows up in the "switch directory" option (and also "Manage tenants") that's from a large well-known corporation I've never had any affiliation with. I cannot "leave" this tenant because I have never had a login. How can I get rid of this without jeopardizing my own default directory/apps, etc. I just want it gone, but nothing I do lets me unlink my account from this company. The corporation doesn't respond (naturally, since I've never worked there and they have no idea who I am). Looks like I can't file an Azure support ticket to get this removed without paying? Any suggestions?
