I did all. My coins was stolen. So far they have refused to refund my coins. Some people have been refunded.
They have a security problem (but continue to blame phishing attacks)

I have used same simple pw with No 2FA auth for a bank for the last 10 years. How come I have not been a victim ? I have never lost a cent.

Coinbase prides itself as SAFE and SECURE and supposedly on cutting edge of security, yet all these stories of coins been stolen.
To make matters worse, they do not show their face, no phone nos to call.

if coinbase is not up to the task, they should get out of the way. All, please do not use their service until it is fixed

FYI, this is how it all begain with MtGox.
