Has called a number of times. Never leaves a message. I answered once and a guy said, "Hi, this is Tom from customer service." I think he was trying to bait me into a conversation about whatever he was selling. I just said, "No, it's not" and hung up.
It's a person behind the computer believe it or not. They're selecting pre- recorded responses, pressing a button for each premeditated reply. I said take me off your calling list and they immediately hung up. So it's not an entirely automated system comma though they do speak through TTS software rather than using their own voices. Sort of a sad attempt...
