Call back gets, "Person you have called is on another line. You may continue to hold or press any key to leave a voice mail message." No matter what you do, the call will terminate in a busy signal. There's no voice mail and no waiting. This is the epitome of a SCAM. The caller is deliberately HIDING. Posts on Mrnumber.com report it as spam. Clearly a number you should block.
Just got a call at 9:00 PM tonight. If it's Directv why would they call this late. As far as I know Directv would have a toll number when they call and not a "971". This number is definitely as scammer number. Don't give out any info to them. Blocked them!
