Dear Ms. Persiano:
First, I am sorry for what you are going through. There are a few in every industry that will do what they can to scam, but 99% of Realtors are hard working, caring people.
There are two ways to go after this particular character. First is to request an investigation by the real estate commission in which the link below is provided.
The next is to file an ethics complaint with the local real estate board who has processes to follow but is very pro-active in the pursuit of what is right for the public. Because I do not know where the Realtor is, I cannot direct you. You may want to visit www.njar.com for that info.
If found that the company has done wrong there are fines, levies, loss of license, etc that would be incurred. And of course you have the ability to litigate and hopefully recover damages if they are found guilty.
I wish you good luck.
