This caller first called from this number in Moorpark, California, and said he was calling about a medical device my doctor had ordered and needed to confirm my address. He then gave me an address I hadn't used for several years. Then he wanted to know my pain level on a scale of one to ten. When I asked why he needed to know that he launched into a high-pressure sales speech. I told him I wasn't interested and requested that he put me on his company's Do Not Call List. I then hung up. He immediately dialed back from a number in Brooklyn, Maryland. I asked to speak to his supervisor but he began berating me about how my doctor had ordered this item and I should give him the information. I hung up. He called back two more times from the Maryland number in the next two minutes. I blocked the number.
