MBD - levels of disgust just keeps going down!

Once again, MBD levels of disgust keeps going down. A very rude, screaming gentleman called (he used cellphone number +***0) my wife today and threatened her, stating 'he knows exactly where she lives. . He is coming.' His tone indicated a threat of harm. This treatment despite payments made each and every month faithfully on an agreed amount with MBD. This is a ******** offense and further action is being considered should MBD not cease with this action.
