I registered to say that the exact same thing happened to me.

I did Cash -> Email, paid at a CVS through Moneygram, when I got home the email that my transfer went through was waiting in my inbox with the url to coinapult. But there was no email from coinapult. And when I click the link to coinapult it says that I have 0 coins.

It's been almost 2 hours since I got the email and no change.

Emailed their support address, hopefully will get some kind of response.
