You can call or email your agent. I recommend talking with them, letting them know your reasons, etc. Also, if you have anything in writing from them as your Agent, you should also put it in writing of your termination. There is a form for this that your current agent will have access too.
If you are then looking for another company and agent to work with, I'd be glad to meet you and let you know how I work, and what your expectations may be of me and vice versa.
I'd be glad to help. Feel free to call, text or email me anytime.
