I once got charged for a office apt to a Dr. I didn't even know. Through research, I found that he assisted during my c-section AND was paid! I called the office to say I didn't even know where they were located and surely hadn't been there. The receptionist was extremely rude insisting that I came for an appointment! So, I wrote them a letter which was answered by a threat of collections. I reported them to the BBB and got a swift apology and the bill was history. What a load.
