Has anyone ever dealt with CBCS? They called me the other day to say that I owe Comcast $407. Of course they wanted all my information but not before I got all the information from them first. The cool part was that it through her off when I started asking the questions. Then I think she hated it when I said that I was not acknowledging the debt. She proceeded to say that I had spoken with them in the past and had made many promises to pay and have broken them. I've never spoken with them in the past.
