These calls need to STOP

I have rec'd numerous calls in the past week from this #. When I pick up, I receive no response, just dead air! If I don't get the call, no v/m is left. I called the above # jusrt now, listened to the options availiable( NLOT one to stop the calls , BTW) & spoke w/ a support technician, asking him why they keep calling. He said he couldn't figure why the calls were being initiated, & had no notes on my account, either!! Then, he put me on their "no call' list!!  Maybe I can get some peace now!! We will see.

got two calls from them this afternoon. No message.Just says ID not provided Really annoying.

That number keeps calling my cell phone and hanging up when I answer

DirectTV sub-contractor

This number keeps calling my mobile number and when I answer, they hang up or they don't leave a voicemail.  If it's DirectTV they should either speak when spoken to or leave a voicemail.

same problem as the others. This number calls me and when I answer it, they hang up.
