After a few failed Uber pick-ups and one instance of a mysterious 27% post-ride "corridor fee", my policy moving forward was to simply no longer do business as a paying customer with any business that doesn't have actual customer support.
This meant, among other things, migrating off of Google, a few brokerage accounts, and one national bank.
Doing a "support test" is also now one of the very first things I do as a new customer of any company.
So far, I have zero regrets. In a perverse way, I give Uber credit for providing the impetus for those decisions.
