Robocall regarding mortgage refinance. it was very intelligent and natural sounding. responses were based on my voice input. I thought it was a real person for 30 seconds. hung up and then they called again couple hours later. I did not make a sound and then they hung up after around 5 seconds.
This number has called me 7 times within three days, all at different times throughout the day with the latest around 9pm. Caller hangs up as soon as I answer.
