How do you stop collection calls for family members or x husbands or their family members?

When a collection agency calls you can inform then that "x" resident no longer lives their and you wish for the calling to cease.

Otherwise, If the calling does not cease you can contact the FTC (Federal Trades Commission) and file a harassment complaint.

If all else fails and the calls continue despite your many attempts to have the calling ceased it would be in your best interest to have your phone number changed.
