This collection agency is looking for the former owners of the repo I purchased from the bank. That's what happens when number is listed. Each call I recieved is date/time stamped on my end.
I got a call from these people and when I called back they started reading me a list of names, asking if I knew any of them.
These people employ illegal tactics, they are reverse looking up addresses and calling anyone that's nearly a remote match. Had they performed their due diligence they would have seen the people the are trying to reach simply lived at one point in my apartment complex. But their matching system ignores Apt #.
LESSON: Pay for unlisted phone #. Don't live in apt. complex where anyone has owed money.
