I was pleasantly surprised to find that when I called this company back that they were searching for another man with my husband's name but different ss#. The collector was nice and courteous and told me that she would remove us from the call list.
I wasn't mad to start with, so I think that makes a difference in how you are treated.
We'll see if they continue to call us now, it could go the other way quickly. They only called us a few times and left messages, but I knew we didn't owe anyone.
