I am so upset with coinbase at the moment. After waiting five days for the bitcoins to get processed, with 1 hour to go, I get an email that the transaction was cancelled due to high risk. It just so happens that bitcoin price surged $8. This is unacceptable in my opinion, I have also emailed about this and am still awaiting response. Now I am forced to place a new order at a higher price and hoping this one does not get cancelled too. I would think twice before using this service. My cancelled transaction # was A0WYIHD9
Send them a support request and complain. That definitely sucks, but they've freely admitted that it's an automated system and it makes mistakes. That's not excusing them for it, just saying that it happens.
Also, when I bought my bitcoins from Coinbase, the price went up at least $10 from when I placed the order and when it came through, and they still honored the order. Just FYI - there is more going up than just the price going up, although that may well be part of it.
Yeah, hopefully you didn't place a new order at a higher price as they will honor the original price. BTC was up a little over $20 when they corrected my original canceled order. Also don't expect a quick response to your email. They are working to improve customer service, but it is currently pretty slow.
