Apple not responding about upgrading to Organization account

Hi all,

I obtained a D-U-N-S number, confirmed that it's available for lookup, and submitted a request to upgrade to an Organization account 12 days ago. I then followed up 3 days ago. Still haven't received a response.

Does anyone know if there's anything I need to do to get a response to these inquiries?

Only reason I'm upgrading to Organization account is so that multiple developers can sign debug builds for physical iPhone devices so they can collaborate on my project.
