I asked to be on the do not call list yesterday, they advise they will not call again. I had another call today and they said they will keep on calling me until i purchase something from them. I told them it was illegal and he called me a liar. I asked to speak to his supervisor and he told me i need to call the company that is calling me. I advised him that he was the one who called me. I contacted my phone company and blocked them. They are trying to sell medical supplys.
