This number started calling late last week and on Friday (2/5) called 8 times! Fortunately my answering machine logs all the calls. Called them back like you, spoke with what sounds like the same lady. I kept asking after her initial Integrity response, she finally coughed up Integrity Financial Partners. A Google search indicates they are a debt collector.
got a missed call from this number. *67 and called back and the lady who sounded like a young black girl wouldn't tell me what kind of company "Integrity" was. She asked for my name, and I asked her again, and she said she couldn't disclose who she was without me disclosing who I was. pretty crooked if you ask me- they called ME!
