...and Coinbase directs you to send a physical letter when their voice chatbot fails. Seriously. I had a login issue preventing me from accessing tax forms and the phone tree eventually got to the point where a sane provider would hand you over to human chat.

When the Coinbase voice agent gave me an address to mail a letter to and hung up, I was so shocked I had to call back and go through the process again. I was told to mail a letter describing my issue to an address on 5th Avenue in NYC.
