Send it to the email address that they told you to send your information to. ![Smiley :)](https://www.talk.uk-yankee.com/Smileys/classic/smiley.gif)
Don't use the paid for email address.
They emailed me back already (SHOCKING!) and said that they have not received the documentation and that they are in fact still waiting. I wrote them back, told them the dates from the original email, copied the original email, attached the PDF and sent them a screenshot from my sent mail folder showing the original email that I sent to them 8 days ago.
This process is AGONIZING. I don't understand how this can be this hard. I know that I'm preaching to the choir here but JFC.
