The agent should stand beside you to the termination of the transaction. In Texas, the agent is only an extension of the Broker. Contact the broker who is holding the license of the Sales Agent. It sounds like what happened to you happens daily in this business. A lot of agents don't really understand what is really in the terms they fill out in the contract.

The Broker is the poerson who is held accountable by the Texas Real Estate Commission.
