Scam.  Offering compensation from using a certain type of birth control.  When I asked who was offering the compensation the call was disconnected.  Obvious call center, likely in India.
also calls from:  240-431-9979, 786-512-8878, 818-297-0908, 599-331-4564  
Calls originate from East coast to West coast and everywhere inbetween.

Received calls:

The only callers I could actually understand enough to get what they were REALLY calling about were from today. But I know they were all calling about the same thing.
It's supposedly a "compensation" program regarding Yaz, Yasmin, and some other birth control (unintelligible). In the two calls today, they asked if I've had any blood clots or minor strokes. I haven't. The first call bid me goodbye and blessed my day, so I expected that would be the end of it.
Until 20 minutes later when they called AGAIN.
So frustrating!!
