In Real Estate the agent actually works for a person with a higher level license, called a broker. The broker is LEGALLY responsible for the performance of their agents. That means that IF the agent DOES do something wrong, the broker may be held legally liable for damages.
I would find out who the agent's broker is and contact them. Explain your concerns. It is in the broker's best interest to help you get through this transaction.
If the agent is a REALTOR, then they are required to adhere to the Code of Ethics. You can read the Code of Ethics at http://www.realtor.org. If you think that they have violated the code, then you can file a grievance with the local board of Realtors. The Association has a hearing process that can result in different levels of punishment for violations.
Have a great day,
