IF the franchisor lied to you (e.g. information was exaggerated or completely false), then that knowing misrepresentation (lie) about material (important) facts may constitute fraud, which could give you grounds to sue them for all your losses. If the amount at stake is several thousand (or tens of thousands) of dollars, consult with an attorney about seeking recovery and vindicating your rights. If less then $3,000, you probably want to work with them, even if you were wronged, to resolve this as best as you can, since you'd likely spend more  on legal action than you could recover. Good luck.
