That being said I really encourage you to talk with your agent about why you want to terminate the agreement. If he/she is not meeting your needs a good discussion with them may be all it takes to get the agent to do what you need them to do to help you to find a home. Your agent may not even realize that he/she is not meeting your needs. Good Luck!

I would go to the agent and ask them to cancel.
Tell them the reasons why.
If you are not comfortable doing this go to the office manager or broker.
Why are you trying to terminate?
If fit is bad, just tell them.
Maybe broker can get you a better agent.

As long as you have not seen any homes that you a interested in, then a simple letter to the broker should be sufficient to terminate the agreement.
If you have seen a house with the agent andw may be interested in putting an offer in on it, then you will need to talk to the broker because technically any house that the agent introduced you to will entitle them to commission if you decide to buy it.
