dpaulsmith,
Here's the number I got from my online order receipt and you can call them to confirm your order: 1-800-639-6114
You can also try the status site:

I'd still call and have them confirm you did not order twice, you should NEVER refresh when placing an online order as it may have gon through the first time.
Call them and keep an eye out on your account/CC activity.
