Another one of those annoying "You've won a cruise to Bermuda!" scams! And, based on the script of the robo-call, they obviously know they are violating the 'do not call' registry listings. When you fail to talk back to the recording, it then says, "Sorry, we didn't hear you. We will take your name off our list..."
Oops! The phone number with the scam phone call was actually from 317-489-0143, and I thought the thread of messages that I was replying to was for THAT number. Please pardon that oversight. Thank you. .
