At some point in time a client will want to terminate his relationship with you. Nobody is perfect and sometimes things can simply get side-ways, regardless who is at fault. It happens. The most important thing about being told "I want to use another Realtor" is to remember to remain professional and to retain your full composure.
Remember, part of a Realtors specialty is to help remove the emotional deposits that can be made from a real estate transaction. It's important to be candid when you wish someone well who want's to "go a different route."
Last week I ran into Betty Bookmark, a former seller who kicked me to the curb almost 2 years ago. She and her husband chose a different listing agent and immediately sold the home for more than asking price. Of course I wasn't happy, but I was proud for not acting like a dramatic fool on the way out. When I ran into Betty she offered me the name and phone number of a person she works with who is looking to sell their home.
I have an appointment tomorrow evening with Betty's co-worker.
