Harrassing most terrible unprofessional company

This company has been harrassing Mr non stop for 2 weeks looking for someone that I do not know. The Morris tried to tell the people that phone me I do not know this person. The more they phone me up to 3/4 times a day. Not even my own mother phones me so much. They do not do their jobs. They did not make a note that they have the wrong number. They just kept on harrassing me. At first I was nice to tell them they have the wrong number...that did not work. Then I was a total *****. And that still not work...one of the woman that phoned me...even spent time phoning me back that I was rude for a big person. There is absolutely no professionalism in that company.
