I did, unfortunately.  Tried to take my money out back when TF threw up the "this is a demo, none of it is real" wording, but unfortunately I had already renewed my CD by that point and he was going to charge me 5% of my principal to take my money out.  Which felt a bit ridiculous given that he was changing the rules part way through the term of the CD.  In retrospect, I should have argued more forcefully at that point, but it might not have done any good if I had anyway.
