Who called from 2019847867

201-984-7867 called me.  Here is how conversation went down:

Me:        "Hello"
Caller:    *pause*  "Hello?"
Me:        "Hello!"
Caller:    *another pause* "Hello?"
Me:        "What?"
Caller:    "I said hello twice."
Me:        "So?"

Caller then hung up.

Ive since called them back several times, and have gotten an answering machine/voicemail, or they will answer and hang up.  Bizarre.

No one there. Eventually they clicked off.

Answered call; Music played then electorinic voice says "Thank you and goodbye."

Called me twice. First was hang-up.  Second was playing music.

I have been getting calls from this number to my cell phone for the past 2 weeks or so. They always hang up. The first time, I called back and received a voice mail. I just received another call from them, so I called back and told them that I was receiving calls from them and if they wanted to talk to me, then do so. Otherwise, please stop calling and using my minutes.
