How much can an "AU" do??? Can an "AU" ask for an upgrade for the card??? What about a limit increase??? ...or do they just have permission to charge on the card, and that is all???
From my experience, an AU can only charge on the card and send payments in (hehe). I've been an AU on several of my husband's credit accounts. Whenever I called the CC co. to ask a question- the rep always had to speak with my husband first to make sure it was "ok" to share the account information with me.
