Communication tactics: Debt collection

Ability recovery services located has been calling me every day sometimes two or three times a day. They are reporting on my credit about a medical debt that occurred last year and I had insurance and they are claiming I didnt. I am not with the insurance anymore. I called and said I was calling to find out why they were calling me repeatedly and reporting on a debt that I shouldnt have. The woman got a harsh tone and told me that I didnt need to call with the attitude which aggravated me and I told her I didnt have one she said yes you do and I replied if she wanted an attitude I could show her one. I asked about the debt she told me who the original creditor was and asked if I wanted to take care of it I said no and they needed to stop calling me every day she said ok well when you are ready to pay the debt give us a call back and hung up abruptly.
