I had one of the most incredible, yet scary, scam calls ever yesterday afternoon.
It came from someone claiming to be an energy representative for my area and wanted to ask me some questions.
After every pause in the person's sentences, I noticed there was a noise. This lead me to conclude that the voice was artificial even though it sounded genuine and not robotic.
I then started shouting 'excuse me' repeatedly down the phone while the 'person' was in the midst of saying something just to see if it would react in any way.
