I was supposed to receive nearly $700 in my checking account today for selling BTC to coinbase, but it never showed up.

Support has not bothered to respond to my emails.

This has happened after I have had BTC that I tried to transfer from coinbase to another wallet completely disappear on me after never even registering on the blockchain.

So are they scammers or just incompetent, or both?

Do they even have a phone number??? How about a physical address I can show up at??

Can anyone help? This has caused me to lose complete faith in cyptocurrencies in general.
