Reading your original post I would say you were not well represented. I am going to assume that when you made the original appt there was not an offer. While you ASSUMED the agent would call you if an offer came in (which is valid) it does not sound like you told the agent to do so. However I agree that the representation was lacking and the performance of the agent was deficient. It may be a good idea for you to call the broker and present the situation to see what happened. At the very least confronting the agent and asking why the heck the agent did not call you immediately upon receiving an offer on a home you were CLEARLY interested in.
Poor performance based on your description of events.
