When I expect a Robocall or Telemarketer I answer and follow up immediately with ################################. I seldom get a second call from the same number.
Same here. Very slick robo-lady claiming to be from Visa, telling me that, "due to my excellent payment history", I'll be getting zero percent interest rates on all of my accounts. I like stringing these snotrags along, so I pressed 1. Sadly, got double-busy so no fun and games.
