I repeatedly get messages from this number referring to a person who does not live here (obviously they have the wrong number). When I try to contact them and tell them they have a wrong number and to quit leaving messages on my phone they tell me it is their job and hang up on me. They appear to be a collections company of some type but I do not owe any money and they say the message is for a person that is not me or my family. How do I get them to stop??
