"Not Available" was the caller ID, it plays a little chime after my No Solicitation message ends and they disconnect. When I did the return call, there was no message, just silence.
Just received a call from that number on my cell phone. Will block it. I have now blocked the 312-340 . ... multiple times as the scammers always change the final digits. Cannot figure out how they have my number. So much for "Do Not Call".
Robo call stating I have won a fully paid cruise to the Bahamas that will be rewarded to me after completing a survey in which my name was specially selected. I hung up at that point.
