Best of luck to you!
Wishing you the best,
We aren't lawyers, and they can be expensive, so I've attached a link to the New Jersey Landlord Tenant Law. Without more information no one can really advise you beyond looking into your rights and seeking legal help.
Start by reading over the link and searching out specifics that will apply to your situation. Once you have a better idea what the law is, you will either know how to handle this yourself or be in a better position to speak intelligently with an attorney. Best of luck.
