UPDATE: So, I just got a call from the personal trainer. I had left him a message to let him know that I wasn't interested in the program - but he claims he never got it -- and that's a possibility. It wouldn't be the first time I've left a message at the wrong number. Anyway, I reiterated that I could not afford the training, that I would be doing this on my own, and that I might consider revisiting the idea of a personal trainer in six months time. He then proceeds to tell me that I will fail on my own because everyone else has.
I really didn't feel like talking with him any more, so I did not point out that people do succeed on their own, that his gym is running a bait and switch, and that I really didn't appreciate the attitude. I will, however be registering complaint with the gym on their sales practices. Not that it'll accomplish anything.
