Worst attorneys ever

I am so sick and tired of these attorneys. They keep on sending me threatening messages for two Dr;s accounts but they do not want to send me the statements or who this is for. I have medical aid and nowhere on my medical aid statements does it show that this was not paid. The one Dr on their SMS's I do not even know, but still they keep on threatening me every day and every day I ask for the statements and more detail and they just ignore me and keep on threatening me.
