Was your agent a Realtor, or a licensed real estate agent? If this person was a Realtor, a member of the National Association of Realtors, there is a very strict Code of Ethics to which they must adhere. If you feel that you were mislead, please contact your local Board of Realtors and let them know. If the agent is a Realtor, they will help you file a grievance, which will be reviewed by a panel to determine if there is grounds to to proceed to a hearing. It is essential to hold a professional accountable, and you are likely to find your local association takes consumer complaints very, VERY seriously.
If, however, the agent was NOT a Realtor, then you might want to report their actions to the state board of professional licensure.
