Netflix US charged our new Citibank credit card at least 3 times based on a fraudulent purchase (somehow someone had made a Netflix account with our credit card number). On top of that it wasn't even activated because we'd stopped using Citibank to simplify our accounting and just hadn't cancelled entirely yet. Backdoors exist apparently for recurring charges that roll over onto new cards for "customer convenience" because you wouldn't want to miss your bills and lose access to Netflix.
