Not making excuses, but keep in mind that it could be a genuine mistake by the lawyer or one of their employees as well. I wouldn't point any fingers until you know more about what actually happened.
Whether or not the records were actually released for the whole 7 years is also important. There wouldn't be anything to gain by raking people over the coals for a genuine mistake if the records weren't released. Trying to do so would likely make you look petty to the courts.
