They have a ton of numbers. I get called once a day from at least one I even talked to a person and asked them to stop calling me. The next day I was called by a new number.
I receive a call from 515-421-5843 daily. I wait for the recording to stop so that I could press the prompt to speak with a live person. When I get an opportunity to speak to a live person, I have asked them several times to place me on the do not call list. Most times the person would hang up the phone and not acknowledge my request.
