totally screwed me too.  I bought 6 bitcoins they deducted the money from my bank account right away.  8 days later when I was supposed to get them i get an email that they cancelled my order:

On Jul 5, 2013 you purchased 6.00 BTC via bank transfer for $419.99.

Unfortunately, we have decided to cancel this order because it appears to be high risk. We do not send out any bitcoins on high risk transactions, and you will receive a refund to your bank account in 3-4 business days.

Of course they had gone way up in price which was the whole reason I bought when I did.  I had made a transaction for 1 bitcoin in the past and it went through no problems.

I finally got a reply after many emails:
 
Olaf replied:
Hi,

I'm sorry for the trouble! I can appreciate how frustrating that must be. I've whitelisted your account - this means your transactions will no longer be flagged as high risk. You shouldn't have any problems going forward - let me know if you want me to push through the cancelled transaction at the original exchange rate.

Again, my apologies for any undue stress this has caused you!

So I immediately replied YES, push through the transaction at the original exchange rate and do not refund my $ to my bank account I want my 6 bitcoins. 
Never heard back, have written emails everyday asking the status and when will i receive my bitcoins...in the mean time they refunded my $419.99 back to my banking account.

VERY UNSCRUPULOUS BIZ...I am still waiting on a reply from the the last one from Olaf days ago.  I sure hope they honor their word and "push through" my cancelled order at the original exchange rate...otherwise...These guys are just complete scammers
