United Collections Bureau, UCB They called my house several times attempting to have me contact a neighbor about a pending legal case Columbus Ohio

I was contacted first by UCB by a message left on my answering maching advising that they are attempting to contact a neighbor and his wife regarding a pending legal case. They left the customers name, address and case number and asked that I contact them immediately and/or leave them a note to contact the company. Shortly thereafter, my 17 year daughter came home and received a call from the company. The lady got very upset with her that she did not know who this neighbor was. Later in the afternoon, my husband received a call where the man was very unreasonable. When I got home and got the different stories from the family and played the message several times-I called the company and advised them that if they wanted to take the appropriate action-then file a legal case or contact them by mail. It is not the neighbor's responsibility to be a collection agency. He advised that me that if I choose not to contact the neighbor that was my business, but in the meantime they were going to continue to call.
It would be very embarrasing for the neighbor, if I went over and told them this company was contacting all theri neighbors. Although these folks have made me so angry, I would like to file some type of claim against them.
They got my name from a neighboorhood search and online phone look up. I changed my name several years ago, but the phone company has not updated the phone listing. I am okay with that if people like this call.

What else can I do to take actions?
