Debt collector selling debt collection services.  Went by the name of Adam.  Nobody owes me any money. He just wouldn't take that for an answer.  I told him several times that NOBODY OWES ME ANY MONEY.  I finally yelled it at him and hung up.  What a dingleberry.

Called says he was a debt collector then when I went to get who he asked for he hung up the phone.

This guys calls me pretending to be a Private Investigator/Debt Collector, then reveals that he is offering his services for debt collection.
Very rude, dishonest, vulgar, pushy and annoying.
