They call 1-4 times per day trying to sell a cruise to the Bahamas. When I try to call them back it is almost ALWAYS busy or they try to connect me with another department to see the cruise.
It's a classic junk call from a robodialer "..urgent message for you from your electric company...". I get one like this every month from a new number every month or so.
Received call from that number but the call blocker (My Number app) on my cell phone identified it as a potential spam. It's a great app for blocking spam.
