312-893-4857. It's Harris & Harris - a debt collector. I had a doctor bill for a long time ago that was paid off and they are still calling me...... UGH!!! They call for a lot of different numbers with the 312 area code.
It is a bill collector. They used to call me about this bill (it was a hospital bill of my father's) years ago and I told them (several times) that it had already been paid. Now after 3-4 years they called and left a message on my phone. So - not only was the bill paid years ago, my father has been dead for over 2 years and his estate probated and probate closed. There is no way they are getting any money on this.
