<prompt> Human: Last year, a debt collector sued my father over a small but valid debt, everyone went to court, and the collector lost on the grounds that my father has full medical disability, cant work, and has no income he doesnt even qualify for SSDI. Seemed like a pretty clear cut end to the story.Fast forward to last week, I and apparently other family members started getting daily robocalls from this same collector trying to find my father Find? He hasnt changed his phone number or address in 15 years, shouldnt take too much work to find him!. So far Ive just let it go to voicemail, but my patience for this wont last long.So my question - Should I just demand they stop contacting me; should I answer and treat them like I do most other telemarketers basically have as much fun as possible wasting their time; do I actually have any take-the-offense legal options; or something else entirely? And although my father doesnt count as the litigious sort, can he initiate any legal action against this collector for their obvious attempts to harass him despite having already fought this battle and lost?I dont mean to defend him for not paying his bills I give him enough hell for that already. But from my perspective, this has gone way too far and theyve made the mistake of involving someone me who actually has the resources to fight back.  <response>: Familiarize yourself with this information and take proper action
