Well, if you
really want to straighten this out, you could call the AAMC accounting office. Their number is 202-828-0451. Are you sure you really want to, though?
P.S. I regret to inform you that those dates after your designated schools do not mean that those schools have a copy of your application. They merely mean that AMCAS has notified those schools (probably all of your schools, they just leave some out to confuse you) of your intent to apply. The only info the schools are given is your name, address, e-mail address and state of residency. This is considered preliminary information. Later on (
much later) after your application is verified (which will probably only happen after you threaten legal action), your schools will receive a summary application (which will not include any of the essays you labored over, nor, in some cases, your MCAT scores).
Much, much later they will receive either electronic transmission of your complete app (that is, the approx. 1% of schools currently capable of receiving electronic transmissions will) or a FedEx'd paper copy of your application, (which you've probably already sent the school).
Now, are you sure you want them to charge your credit card for this service?
