coinbase is NOT doing a good job. I try to withdraw some coins since the 18th and all i get is a pending transaction and 24 hours later an email that my coins are refunded because my transaction is still pending.
It is ridiculous.
I am trying to withdraw some BTC from there as well... and still waiting.
There is no sign of any transaction for the address I am trying to send to at blockchain.info so they are just refusing to send it for some reason.
