Lol..i think you should take it easy buddy and really explain the issue well because this is indeed the first time I am seeing such review about coinbase. Anyways i haven't used coinbase before because it id not available in my country but i haven't seen such a review before. Just take your time and contact their support again and see if you can get your money back.
But you're right. We can't trust any of them crypto exchange..we gotta be careful always
