Just a very small note on this:
It is very important to avoid posts being removed for the kind of words one chooses to use. Do not insult people you wish to speak about, even if you are speaking about the worst person in the world. Recount the details and facts of your experience that you wish others to be aware of, and hopefully your poor experience will serve as a warning to others, and save them from similar disappointment.
Please feel free to share your story anonymously as a guest. However, may I suggest that you register with the site, and log in before posting, so that a genuine name is attached to the post, which will make it so much more effective and powerful.
