In the last few years I have received repeated calls from various collection agencies for a debt that is not mine. They are calling for my ex husbands son. I have been divorced for XXXX years and he has never lived in my home and I have no relationship with him. I do not know how he continues to be associated with me or my family since the marriage was disolved a long time ago. When I ask to speak to a supervisor, I get disconnected. I have asked for them to stop but it seems to shift from agency to agency. Any adivice you can provide would be greatly appreciated. None of the agencies will tell me how they got my name and say it 's to protect their client.
