First, congratulations on your upcoming Disney trip. It is just around the corner.
I believe what the DDE CM is referring to is Guest Services at the resort. I have noticed that many of the resorts now refer to Guest Services as Concierge. I believe this is what he/she is refering to.
With regards to the DDE Card itself. When you travel within four weeks of your DDE Card delivery date, you can pick up a temporary card at the Guest Services window outside of EPCOT. You need to have your AP or AP Voucher and Driver's License with you for identification. I did this myself about a month ago. I received my actual DDE Card in the mail about four weeks after I ordered it. If you are traveling before the DDE Card arrives, Disney does issue a temporary card that can be used immediately. The only way I know of obtaining that card is to pick it up at EPCOT. Just make sure to let the DDE Dept know that you do want a temporary card issued so that it is there waiting for you, otherwise you will be out of luck.
