Just got a call from 202-564-2881. Caller ID says it's from US EPA.  I called the number back and got message.  This number is not in service.  So definitely some sort of scam.   Beware.  

I just got a call from a man with a heavy Indian accent from this number, which came up as "US EPA" on my caller ID. He asked if I'd had recent bladder surgery, so I asked to be taken off his calling list. He told me no, and that I must answer if I'd had recent bladder surgery. I told him I don't have to answer his questions and again I asked to be removed from his calling list. He said I can't be removed because he's with the US government and he needs to know if I've had recent bladder surgery! I told him again that I don't have to answer questions and I don't want him to call again and hung up. Weird!

Some Indian guy has been calling me for MONTHS. He has called me on several other different numbers as well.  Everytime he says the same thing.  He fishes around for information about my medical history. He will say things like I am aware that you have experienced complications with birth control or have had recent surgeries. UM NO SIR. Everytime he calls I tell him to stop calling me, but he continues to call from different numbers. Now I just don't even answer.
