If you read posts in this forum about Coinbase you'll soon see that the exception to the rule is decent service from them...mostly their service sucks.  They almost never respond to questions posted on their site, through e-mail or coindesk support tickets.  What you'll find is that, even if eventually you do get verified, when you attempt to actually make a purchase, it will be cancelled six days later...and for no reason, and you'll never be able to get an answer from them to find out why.
