I would try at the park but I am back home in PA. I didn't realize the price difference at the time of upgrading. The guy on the phone just thought I was nuts or stupid maybe both. I tried to explain that if the ticket was sold to tickets at work for 3 dollars cheaper and I have to pay the difference that 3x2 was not $60.
As is the case with just about EVERYTHING related to "CM training,"
you WILL be able to get the proper results, but it may take some perseverance.
You will likely get different CM's on the phone with each call.
Call back, call again... and again.
Explain exactly your situation, and do so until you get the proper response
(that you will be refunded the amount over-charged.)
This may take the form of a "file" in your name that will be implemented when you return to WDW.
I know of what I speak.
But, again, it may take some TIME on your part.
Just keep at it... even at your leisure.
You were over-charged due to CM mistake and/or incompetence.
You should not have to suffer the over-charge.
