Not only do I think you should fire her, I think this should be reported to the broker and the local association.
I would be horrified if a seller client of our company called me and reported such behaviors. I don't even know how to categorize the "taking a shower" routine. Other than to tell you I was horrified to read that.
Helping herself to coffee and leaivng coffee mugs in the sink is just plain rude. I wouldn't do that at the home of a good friend.....not even a thought.
Allowing people to tour your home unescorted is a failure of her duty to you. An agent has a responsbility and allowing buyers to run through unescorted is completely unacceptable.
Telling a buyer there was another deal that is better down the street is a complete failure of her fiduciary duty to you as a seller client.
As a broker, I would do the following....
First, I would I would request that you jot a few of these things down in writing, sit down w/ the agent and discuss this situation immediately. If the agent did not deny the actions, I would terminate the agent. If the agent presented another story, I would investigate further before taking action. I do believe you, though. I don't think someone would make up such outrageous behavior.
I would ask you to allow our company to continue to represent you. I would request the oppty to service your listing properly and go above an beyond any level of extraordinary service. If you insisted you did not want our company to represent you, I would release the listing. Your highest level of care may come from the current broker. I would also probably reduce your fee to compensate for the service failures.
Mh, I do think you should report this agent to the local association office. The person seems to not think there is anything wrong with her behavior and perhaps only a formal complaint is enough to wake her up.
As you describe the situation, she didn't seem to be embarassed by the shower incident, nor is she embarrassed about coffee mugs in the sink. Frankly, I would know if someone took a shower in my home...and I would be outraged.
Mh.....I still stand on my earlier posts that I won't condemn an agent w/o info....but, sure to believe, I will react swiftly and appropriately. If I were the broker, I would have already been reaching to the agent via every method possible...email, cell, home, number, office voice mail, etc.
As you describe the situation, you have been way more than patient and tolerant. I wish you would have posted on Trulia sooner or contacted the Broker sooner.
