Guy calls and leaves me a message stating if I do not call they will have legal proceedings against me. For What I do not know.

He called me at 3:05pm. He left a message on my cell phone. He said that he was from a law firm and said that I need to contact him as soon as possible. He said that I had an account with my social security number and said that he was willing to help me to settle out of court if I called him. There was also other voices in the background while he was talking

Just hear air..no one says anything

This number just calls my cell phone @ random. They never leave a message. When you do pick up, there is just dead air (silence). You can't call back this number. It's obviously a spoofed phone number.

Received a call from this number and when I answered they didn't respond and wouldn't hang up so I said hello again and they still didn't say anything.
