bill collectors

I just got off the phone with a collection agency/lawyer place. I had insurance for the time they're harassing me about I made that clear and they just keep trying to collect. My personal theory is they've all ready collected from the insurance and are now trying to collect from me too. I could not believe how horrible the people I spoke to there were. I'm going to contact the BBB and FCC. It is unacceptable to treat people like that.
