Your facts appear specfic to you and do not appear to be the basis for a "class action" lawsuit.
The above is general legal and business analysis. It is not "legal advice" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.

There are ongoing class action lawsuits against BofA concerning its failure to provide loan modifications in accordance with the terms of trial modification agreements that it entered into with borrowers.
Your particular situation, however, has many unique individualized facts, and you probably would not qualify to serve as a named plaintiff and/or class representative in a class action against BofA.
That said, you may have an individual action for breach of contract and similar claims. A local lawyer may be able to help you with that.
