There were multiple issues performed by this debt collector. To begin with I got a phone call from this debt collector in which I did not answer. They called from a phone number in XXXX and claimed to be an investigator calling on behalf of XXXX XXXX XXXX ( my county of residence ). She stated that because I have failed to call her back after multiple attempts ( though I have never once received any voicemail or call from this number and can provide phone records to support that ) that she had no choice but to proceed with a detainment order with a court appearance. My voicemail is clearly set up where I state my name therefore there is no confusion as to whether they have the right number. I then received a phone call almost immediately from my mother stating that she received a phone call from the same woman with the same threat left on her voicemail. It is my understanding that a debt collector is only allowed to call a family member if they are unsure as to how to reach the person who has the debt. On top of that I also was under the understanding they are to share no information whatsoever especially the same threats of me getting detained. When I called the number back the same woman answered and never once identified herself as a debt collector but instead stated I owed money. I was frustrated because I believed this to be a debt I had paid to a law firm already and the woman then stated I can contact the company it originated with to verify the debt. When I told her that I was not going to pay something twice she then said she is going to proceed with the detainment and will notify the original debtor and then hung up on me. When I called back the same woman again answer and was very belligerent with me. I asked multiple time for a supervisor while she talked over me before finally sending me to a supervisor. The supervisor was a little more helpful but again never once did either of them identify themselves as a debt collector and it was not until I asked if they were one that they told me so. When I contacted the original company the debt was with they in fact told me it was still outstanding but stated that the company that the woman who called me claimed to be from was no longer in business and that that debt was sold to another company that they are unsure of.
