If they are taking your money out I would not be too worried. However, I would call again and request the email confirmation. We booked for October 2013 this past February right when the Early Escapes offer came out. I did receive an email confirmation the same day as I booked. Also, I get an email reminder once a month a day or two before my auto withdraw which shows my confirmation number, brief reservation details and a breakdown of my monthly withdraw's plus my final payment amount. Hope this helps!
