The legal system does not and cannot provide a remedy for every rude, obnoxious and unkind act that all of us are vulnerable to in our daily lives.
Make a decision about what to do about the debt independent of this man's bad personality and take some comfort in the fact that he will get his -- if only by having to live with his own bad personality all day every day.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
It is spelled harassment. There is no "trying to sue" there is only sue, or not sue. If you are served with a summons and complaint, hire an attorney at once. You could contac the day care yourself, and offer (say) $20 per week. At least, you will learn whether or not they have "farmed out" the debt. Rude is a poor collections technique, as we can all see. IF they daycare has put the debt out for collection, very likely they are willing to accept far less than the full balance. You can offer that, or you can have an attorney make them an offer.
We do not have a client/attorney relationship until you make an appointment, we discuss your case face to face, I accept a retainer, and we explictly agree to enter into representation.
As Ms. McCall points out, law does not have the answer to every problem, including but not limited to rudeness. You might consider contacting an attorney at the firm to advise them that their manager is not reflecting credit on the firm.
The above is general legal and business analysis. It is not "legal advise" 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.
