Get a Consumer Attorney
The National Association of Consumer Advocates (NACA) is an association of attorneys who practice consumer law.
NACA has a list of their members at https://www.consumeradvocates.org/find-an-attorney
Every County Bar Association in New Jersey (and most other places too) has an Attorney Referral Panel, and you get a referral to an attorney semi-randomly. There is a small fee for the first consultation, then you must agree on a fee with the attorney. It helps a lot to find an attorney who is knowledgeable about consumer law, because such an attorney is more likely to take your case.
If your family has a low or modest income, you may be eligible for free legal help from a Legal Services law firm in your area. For a list of the legal services projects by county, see https://www.lsnj.org/LegalServicesOffices.aspx
Is your problem financial? Too many debts? Are you facing foreclosure of your home? You might consider consulting an attorney who specializes in bankruptcy. You can find a list of bankruptcy attorneys who are members of the National Association of Consumer Bankruptcy Attorneys at http://network.nacba.org/advanced-search
