Add User with Access to Support

I've been trying to add a person who can access support for our different devices.

I added them to the Premier online account. They can now control everything in the account but cannot get support.

I then used the portal to make them a "Company administrator".  I enabled all permissions but, still cannot get support.

I contacted Online Chat, but they don't know how to add a person with access to support.

I contacted phone support, but they, too, do not know how to add a person with access to support.

Does anyone know how to add an authorized person who can receive support?
