Billing inquiry Question

Hi All-  

We are a Managed IT Provider and over the years we have setup and configured Adobe accounts on our client's behalf.  A majority of these accounts are tied to one of our company credit cards.  This setup is complicated and requires good documentation, but is a value add to our clients so we continue to do it.  

I'm running into a problem however:  back in June we started seeing a charge for Illustrator standalone creative cloud that I can't reconcile.  I have the bill date, the card that is being changed, and the creditcard transaction # to go on.  I need help figuring out which Adobe client or adobe order number that it is tied to.
