Received a call from this number today (3/20/17) but I didn't answer it. My caller ID indicated that it was from Vacation World. Got a similar call on 3/6/17 that showed it too was from Vacation World. Didn't answer that one either. That number was: 203-307-0539. No messages were left on my voice mail. They are now both blocked and any future calls from those numbers will not even ring on my phone when they call, but the call will show up on my caller ID. I love this phone system that I bought at a major membership warehouse that begins with "C,"
