I answered the phone and it said
"I am sorry that is not a valid extension. Please try again."
What a stupid thing to say when it (some scammer's autodialer) called me! I hung up and marked it as junk, but since it is probably spoofed, I doubt that is going to make any useful difference. I wish I didn't often receive real calls from unknown numbers so I could just ignore all calls from unknown numbers and not bother wasting my time answering a call where I wouldn't be buying anything anyway or providing any personal information because I don't give it to unknown callers. Too bad everyone doesn't do the same thing with unknown callers because then if no money was ever made by sales or ID theft, then all of these calls would stop!
