When I phoned back the XXXX number on the collection call, the person was abusively rude. I told him the person he was looking for has n't worked here in years and to take my number off, and that I thought it was illegal to disturb business with his call, he said that " he knows his business '' and " what are you gon na do? what are you gon na do? what are you gon na do? '' and repeated it in an aggressive manner many times. I finally interrupted and said, " report you right now '' and hung up. The company was Commonwealth Financial XXXX at XXXX.
