No Referral At All

The doctors office called me back a few hours after our visit on monday. I was told that Riley doesn't take doctor referrals and that I would have to contact them myself. http://rileychildrenshospital.com/document.jsp?locid=325

I called the number they gave me and got an answering machine. I was told to leave a message and they would call me back within 5 days. (That was 4 days ago and no reply yet) The message said that they were taking appointments now for October.
