Yes, this is roughly what I'm thinking. My current plan is to see if they can produce this footage (I'm convinced they cannot -- I keep thinking of how much they hesitated when I asked them to be specific about it) and if they cannot I think they would make some sort of concession. In that case

I too get really worked up when I'm accused of something like this by strangers or people I don't know on a personal level. Maybe if a person is very sociable and interacts with strangers often it would not be a big deal, but when you don't, you simply don't have the social fortitude to shrug it off.

I'm actually a pretty sociable and socially confident guy, but I still feel this way. I don't think I've ever felt so insulted and I think I would feel better about myself if I at least challenge it with them. A refund would not just help me get out of the situation financially but feel vindicating.
