I'm not disputing that these options are probably more effective the OP in terms of getting his situation made right (although I'm not sure what the BBB / FTC could do), but the point of "whining" on an internet forum is to give others a heads up about things like this happening. It's remarkable how quickly companies tend to move when their customer issues are aired out in public, and others are talking about them.

I'm closing my Coinbase account today and advising others I know to do the same or stay away.
