Received a call from this number, but I didn't recognize it so I didn't answer it. I let it go to voice mail, but they left no message.  I called back and it went straight to VM, no name or company, and the mailbox was full.

picked up, no one on responded.

THIS IS A SCAM

Could not answer this phone call. It was listed unknown. I called them back because they left no message. Their mail box was full. I am on the no call list and keep getting phone calls from this number.
