I've had three calls from this number wherein a young sounding woman asks to speak to..."sorry..." pause  "sorry...", at which point I hang up. It sounds like a recording.  Does anyone know who this is

these number keep calling me, when i answer it tells me to press either 1 to continue or 2 to discontinue
i pressed 1 and for 2 seconds i heard a crowd in the background noise but that was it then it turned off!

i tried to return the call and was not able to connect.

(i'm using virgin mobile)
