I got a really weird call yesterday from some place claiming to be the medical center where I was a patient 5 years ago (I go to a new place today). I was a bit suspicious simply because it's been years since I've been a patient there. But there are many plausible legitimate reasons for calling me. However the first thing they did was "verify" me by asking for my date of birth and home address. I was disarmed at first because the lady was clearly American, and sounded bored. But I was still hesitant to give up any information on an incoming call. So I asked for some way for me call them. She gave me a phone number... which was the same one calling me, so I hung up. I looked up the phone number, but it was just a random landline from SC (this was a MA based business). At this point I gave up, and decided if I owed some money they would probably send something in the mail. But it makes me wonder if there's a new class of scammer out there with a bit more sophistication.
