I've had the worst customer support experience with coinbase. I'd advise not using their service. They aren't equipped to support their customers. I'm out of pocket $1000 and have been in a "queue" for the last couple of months.
Unfortunately if you want timely support from cb you have to behave kind of unsavory.
Look up their higher level staff on LinkedIn, then email them. You can also do some creative Google searches to find their personal email and contact them there.
Contact them and they will transfer you to priority people who can actually do stuff.
