There are 2 Joanne's in accounting - one does AP - the other AR. So it can be confusing.
This is the one you are looking for - ap@carmentransportationgroup.com. The CFO is Lester - lester@carmentransportationgroup.com
But I can tell you right now - at 47 days - that isn't considered "past due" to Carmen. And Lester will flat out relay the same information to you. They usually don't even reply to AP inquiries until your receivable is over 60. And you'll have to email usually 2-3 times before ever getting a reply.
They are not an easy group to work with - not by any means....
