Called twice.  I let the answering machine take the call.  No message

Didn't answer unknown number. Caller left no message.

Hung up before I could answer.

Called on a Thur. nite at 6:46pm. Caller ID showed "17864058315". Did not ans. the phone and my ans. machine is off so they do not know if it is a working number or not. Got 3 other calls later in the nite with  different phone numbers and different caller ID's that I did not know and did not pick up. Must have been  scam nite.

Called but left no message.
