This jerk called and demanded to speak to a specific person, whom I had never heard of. When I asked him to spell the person's last name so I could check in our database, he did so reluctantly, and when I told him we had no employee here by that name, he went "Ugghh, fine," and hung up.

Collection Agency for Kwik Trip

608-791-2143, called my cell on May 8, 2015.  Did not leave a message.  I called it back and get an automated answer that just says thanks for calling, all reps are busy, please hold....ummm Nope.  Never identified the company or anything.  Blocked.

The number is for Credit Bureau Data - a collection company for a variety of businesses

They call multiple times a day. I never get answer and they hang up immediately after I try to answer.
