I received yet a third copy of the same letter today. I called the attorney but got her voicemail. I did leave a detailed message saying something along the lines of, "I received your letters. As I said before I am happy to pay the medical bills, but your client refused. I will not be filing an insurance claim because I have the funds, but you know that my insurance company would only pay for the medical expenses as well. I am at a loss as to what else to do here."
I would like to close this chapter out, but I guess short of sending them $6000 there is nothing more I can do except let this play out.
Any further suggestions?
