Who called from 2109917231

Got a cll from this number to my cell ph.  Did not leave a message.  Called back the number and it is disconnected.

I just received a call showing this number on cell phone.  No message and when tried to call back, busy signal.

Same thing has happened to me. I keep getting missed calls from this number and a few other numbers from Texas. They never leave a voicemail!

Same thing happened to me, 1/12/13. I try to call back n the numbers disconnected.

I just got a call yesterday and today from this number (02/01/14 and 02/02) .   Tried calling back and said it was "no longer in service or has been disconnected. "  Sounds like a scammer to me!
