A Manhattan law firm committed a “veritable ‘perfect storm’ of mistakes, errors, misdeeds and improper litigation practices” in trying to collect a debt from a Long Island woman, a state judge has ruled in ordering sanctions against the firm.

Eltman, Eltman & Cooper was ordered by District Court Judge Michael A. Ciaffa in Nassau County to pay $14,800 for a series of state ethics rules violations, including “disobeying” a court order dismissing the case by making “harassing” phone calls to the defendant.
