Got cell calls from this # on 09/30/16 and 10/08/16.  Did not answer.  Reading these comments I've found out who this caller is and what he wants.   I'm glad I didn't answer.  They know it is illegal to call, but do so anyway.  No consequences, so far.

Just a bunch of idiots trying to scam people.  They need to get a life.

Just got a call.  I ignored it.  No message. Tired of these calls.  I'm on the DNC list, but lately have been getting a lot of robo calls, and other crap like this.  Someone needs to stop these people because now, they have migrated to cell phones (I don't have a land line).

Call came in on our landline at 1010 CDT, Caller ID showed "Service Call", but they left no Voice Mail. Have been getting intermittent calls from that number since June 2015. The Caller ID varies, have also seen "Unknown Name" and "Frisco TX". The NPA-NXX is a Frisco, TX number group assigned to Southwestern Bell (now AT&T). We never answer, but they keep calling anyway.

Got a recorded call to my cell, showing as from Frisco TX.  I listened to it for "fun" -- it was supposedly related to a "new" travel service called Global Concepts, and was offering a free dinner and free airline tickets. "Press 1 to sign-up, and press 9 to be removed".  So I picked "1" to get their name (Global Concepts) and return phone number in San Antonio (281-305-2639). Then hung up.  Reporting now to FCC and blocking BOTH numbers going forward.  Bunch of jerks ...  It appears use if the local Frisco number was just to get me to answer, although it required I talk to a actual "person" to get their REAL number in San Antonio.
