My thought was much the same as others, but I wondered at the request to contact them with the "order number". To me it sounded like some sort of scheme for you to contact whoever this person is, ( do we really know they are from Chamblee? ) and give them your order number. Then they would act like they couldn't find it but they ask for your credit card etc info so " they could refund you" . Then they would have your payment info and just proceed to use it to charge you again and promptly disappear.
I bet you guys can't tell I'm a pretty suspicious person.
