I'm in the same situation right now. I didn't back up my Authy keys because when I switched phones, the balance on my Coinbase account was zero (still is), so it wasn't a high priority to me.
Now, I'm trying to get back into the account so I can add some BTC to sell it, and I'm getting nowhere with the customer support. For an account with a 0 balance. And I still have access to the correct email, phone number, etc.
At this point it'd just be easier for me to sign up for a new account I guess, but I don't want to have to use a throw-away email for that. You'd think there'd be some kind of easy path to regain control of an account with zero balance, as there's no risk of theft. Nuke all attached bank accounts and the like as a safety measure.
