This does happen from time to time, and it is best to work with someone who understands you. Give your current Realtor a call and explain that you are not happy with the relationship that you are having with them. At that point they will want to probably refer you to another agent in the office. At that point, ask your agent to talk with their Broker to see who would be a better fit with you. You will definitely need to do this IF you have an Exclusive Buyer Brokerage Agreement that both of you signed. IF you did NOT sign anything, then just a nice phone call or email will be ok, but do not ignore the person.
If you would like me to refer you to an Agent in your area, just let me know. I am a member of the Leading Real Estate Companies of the World and have a great resource of Realtors that are in our network.
Good luck on your home purchase and new agent.

If this discussion has occurred and they still are not meeting your expectations then I would let them know in writing why you are no longer interested in working with them. A phone call is a common courtesy however something in writing is usually required if you are under contract.
"After much consideration I don't feel that we are a good fit. I would like to end our relationship. Thank you for your time and effort."
And I agree, it's always nice to know where you fell short.
