I am not a fan of coinbase and I would certainly not recommend them. If you got a problem with their support mailing and keep stalking them once a day, is the fastest way to get your ticket resolved, sure they will become angry but at least your problem will be resolved.
I think Coinbase has become too big and can not handle the massive influx of users all the sudden.
They keep running promotions for new members to join by giving them free bitcoins such as $60 worth of btc one time, but it seems they haven't prepared themselves to offer support for all these new clients. They can not deal with all them with the same amount of staff they had 8 months ago.
