Who called from 2109917231

I have received several phone calls from this number to my cell phone number over the past several weeks but have never answered it as I never answer phone numbers I don't know so I decided to google search the number and this came up. Thanks guys for the heads up. Next time I'll just have to answer and give the person a piece of my mind.

dont know if this is a scam

Just called me today 3/13/14 @4:36PM Pacific Time, no message. I blocked the number. I am also reporting the number to the FTC.

Thanks to everyone here for posting about this number! I ALSO have Directv and have had at least one missed call every day from this number or 210-991-7234. I've blocked both numbers.

Same thing happens to me. They call every night, tried calling back and it says disconnected.
Call blocking them now!
