CID showed Unknown, so I let the answering machine take it. They didn't actually leave a message, but stayed on the line, so the machine recorded boilerroom/call center back ground noise. Scammers.
Received a call today from this number, they were extremely rude!! they did not want to advise what company they were call from, then hung up. Tried to call back several times and they put you on HOLD!
The person keeps calling and hanging up calling back and asking for the owner and hanging up then calls back every two minutes to 5 minutes and continues to hang up
