If these are debt collectors (as opposed to the original creditors) you may be able to take legal action against them if they are violating the Fair Debt Collection Practices Act (FDCPA.) You should discuss these collection activities--specifically what you mean by "busting my chops" with an experienced FDCPA attorney. Many attorneys who do this work, including my office offer a free initial consultation to evaluate your case and if it is viable will take it on contingency, so you have nothing to lose.
