I went through a situation similar to this with Dell about 8 years ago. The guy told me he had no supervisor and that I had to deal with him. I promptly recorded the call, called back and left a message of the call. The same fellow then called me back and said I was rude and let me speak to his supervisor. There is no way I would have spent this amount of time with this person. I would have gotten his name or recorded him refusing to give it to me and called back and promptly went straight to a supervisor and got this issue solved. Companies that have this kind of policy and are ok with these types of employees talking to customers like this quickly loose all their customers to competition as soon as their competition catches up in technology.
