when I answered, as people above, I got a beeping sound. I hung up immediately. That is actually a robocall fishing to see if someone answers or if it is a deadline. Once the robocall has you pegged, the lady calls back later with that survey thing. I've gotten her before. You literally have to hang up. They just don't stop talking whether you're talking or not.
Called back is for Sweepstakes to win a $300 Walmart gift card, plus After I call they want me to start an annoying survey by press telephone buttons, I rather press 3 to opt out not call me back and remove from their phony raffle, survey.
I have been getting these calls for a few months now. I don't know why. But I don't personally answer unknown numbers cause I know recently people have been able to call someone and get information about them just by having them answer the phone. Don't know how, and it seems very scary and psychotic, but it happened to someone I know.But it beeps after a good 5 seconds, and then the beep is a quick 2 second long thing. Then the message ends.
