The debt collectors call and ask for someone that I have no knowledge of, in any way. I have told them they are calling an invalid number, but they have continued to call. I have advised them to stop harrassing me, but they say that I did n't tell them ( the person speaking ) personally so they do n't know not to call me. They are also harrassing my husband and he has told them the same, we do not know who they are talking about and ca n't help, stop calling. It 's been going on for months and they use different phone number, with no caller ID. Sometimes they 'll leave a message asking for this stranger, and we need to have him call them regarding an important file. They will not stop calling us.
