Adding more device lincences to Education account.

Hey, I have been trying to get a response for this, so far I get directed online to your help section to do so. However the help section in education shows you how to deactivate, re-activate and how to create a new package. However to add new device licences to existing account, you need to call an education reseller speciallist. Then i get given a number:

Purchase additional licenses

Currently, the Admin is unable to add (purchase) additional device licenses through the Admin Console. To purchase additional device licenses, call Adobe Business Direct at 800-443-8158 or an Adobe Authorized Education Reseller

Note:

The Add Licenses button in the Admin Console is only for adding named-user licenses. These are licenses assigned to individual users, unlike device licenses, which are assigned to specific devices.

However when i call, they tell me I ca use my admin console and add more devices.... There is no section in the admin console to add more devices, then the agents send me back to the website for more info... this is a loop.... can you guys send me the how to IF I can do this myself? I've spent many hours already calling about this and I'm not getting anywhere.
