Should you call out real estate agent who put their best interest above yours?

Q: We recently sold our deceased mother’s home in Columbus, Ohio. The house needed quite a bit of work, was structurally sound, and was in a very desirable neighborhood.

My siblings and I selected an agent after a couple of interviews, and emptied all contents from the home. In the six weeks or so before it was listed, our agent came to us with an “unsolicited” offer from another local agent, who is also quite well- known and well-connected in the real estate community.
