Say the words, “complaint” or “cancel my account.
You have not received what you paid for? You have the right to express your dissatisfaction. Losing customers and having them cancel orders or accounts is every company’s worst fear. So you can say “cancel” or “cancel account” to the robot. They’ll link you to the appropriate department, or you can describe your concern, and they’ll send you to the appropriate department. You may end up at the beginning or the end of the line, but you will eventually pass the robot.
