To be fair to coinbase.  They did finally straighten out my order and sent me my order

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

Only fair to let folks know, that they finally sent my bitcoins today...took a long time, but I guess this squeaky wheel finally got some grease.  no compensation, but at least i have my money now

I understand that, but they have known about it and have had my support case since 6/12.  I have sent replies to their email everyday since then, multiple times a day and do not get a response.  I can understand delays, but over 9 days when all they need to do is send my money that they have to the address I provided is unacceptable.  But I am glad to hear that some people are getting service and are satisfied, wish I was one of them

Still haven't received an email or reply today regarding my transaction from 6/12/13.  Bitinstant still has my money.  If someone from Bitinstant sees this...PLEASE HELP!  My support  Case #10815.  I have bombarded your email with replies and the address to send my coins to, with no luck.

Level of Support is laughable and unbelievable...you are dealing with peoples money not just goods!
I sure hope someone makes this right real soon

Had a transaction fail to Mt.Gox on 6/12/13 because I provided my account # instead of a wallet address.  I opened a support ticket and after days was asked to provide a wallet address.  I have provided a wallet address since 6/17  No one responds to my emails and my money has been sitting with bitinstant going on 9 days.  In an attempt to find someone to help I have found this forum.  If you are out there charlie...can you please help me...support ticket # 10815  i really need my money.  I have gotten so frustrated with this.  please help and respond to my emails to support...thank you in advance
