I was offering up ideas of why she would be charged for what she thought was a free upgrade. I wasn't drunk or accusing anyone of anything. If you booked as a convention and aren't attending one it is sort of a lie (hey I am doing it too, no judgement) and if Disney has started policies against that sort of thing (not saying they have just again trying to offer a suggestion why she was charged) perhaps they cancelled her convention rate because when asked she admitted to not attending one (I wouldn't know how to answer if asked at check in either). Maybe that happened, maybe it didn't I was trying to speculate to help OP.
If the charge was from the TA because she "owned" the reservation until check in and saw the OP was given a higher room category and charged her for it (don't know why anyone would do that but people get bugs up their butt) then what else would you call that other than spying? I didn't say she did that, I said it was an option for what happened.
As for the magical experience, mine has been a hassel. Yes the price is good, but it caused issues with booking dining and the TA shrugged off my frantic plea for help on adr day and said she would put the adrs I didn't get on a watch list (so so glad I did them myself instead of trusting her because I got several that she was watching for and never did anything about), I can never get her on the phone to make a payment (she never calls me back either so I have to keep calling until I get her which is annoying) vs logging on to
MDE and just getting it done. So far I have yet to see any service advantage to having her as opposed to doing it myself and it adds unnecessary worry to my upcoming trip because I have to watch everything to make sure she does it.
