When I call back it says non working number? Yet I keep missing calls from them?

answer.. nothing... hangs up... STOP!!

Same thing for me but I've answered the call twice and they said my name but I told them I wasn't her and told them I was someone else and they kept hanging up.

got a call from them today......said they want to send me some american money......told them i would have someone call them back in a few minutes...they stated they would call me instead....i tried calling and got no answer.......their number needs to be disconnected if someone could do this......

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!!
