We are not permitted to represent JA's customers or to refer any particular attorney to them. However, this link may help you find the lawyer you need. It appears that you need to pursue a breach of contract suit and/or a declaratory judgment action to obtain a court order to have the lien rendered null and void once the offset is applied to the purported balance due.
Here is the law:
4:42-3. Declaratory Judgment
A judgment for declaratory relief, if appropriate, is not precluded by the existence of another appropriate remedy.
N.J.S.A. 2A:16-53 states:
A person interested under a deed, will, written contract or other writing constituting a contract, or whose rights, status or other legal relations are affected by a statute, municipal ordinance, contract or franchise, may have determined any question of construction or validity arising under the instrument, statute, ordinance, contract or franchise and obtain a declaration of rights, status or other legal relations thereunder.
Here is a sample complaint to use as a go-by.
