Don't know if this will help, sometimes I've found when dealing with customer service reps from India, Pakistan, Phillipines, where ever. I ask to speak to a supervisor, the CS reps basically seem to be reading from a script. If it ain't on the script, they can't help. I have them tell me, "You don't need a supervisor do handle this."
I spent a day going round and round with a satellite radio call center once. Guess who doesn't have sat radio anymore. I've had similar problems with other places, tried hanging up and calling again, once actually got a cs rep in North Dakota!
I was actually able to explain my problem to her, (since she understood american english), and was able to get the problem resolved.
Good Luck!
