All of them have a supervisor or superiors of some sort. But in some companies they do not touch the phone, they overseer the process. I can tell you from personal experience that if the customer support doesn't solve the problem then there isn't a next "level" of support called the supervisor, but only more formal options to communicate remain; think complaint department, mail, lawyers.
