No one on the line, no message left when I don't answer.
Googled the number which lead me here.
Reporting the number and hopefully blocking it as well !!

Have called twice today. Did not answer. Left no message

Even since AT&T took over DirecTV, they've all become anal sphincters.
They're losing money (customers) as they raise their prices to pay off the employees they let go because of the merge.

Received call for free DirecTv premium channels, I indicated not interested. Samantha persisted with her message even after I indicated again I was not interested.  Near end of call, she said the service would be activated within 24 hours.  I said, No and hung up.

This number calls each day between 12 to 1 PM. There is an actual robo response when I dial # (scammers aren't very smart, but they know the scam smarts) asking me to leave my name and someone will return my call. I responded once.
I believe DirecTV should bear some responsibility for prosecuting these persons who do this, as impersonating an organization or another person is an FCC violation and they can be prosecuted.
