For a change, this was not a robo-call. Instead, there was a pleasant sounding woman, in a call center with lots of other people talking around her, on the line. She said her name, but not the company she was representing. I was expecting a different call at the time, so I didn't say anything and left the phone on mute, until she hung up. I'm hoping she marks my phone number as an "open line" or "iinvalid" on her sheet.
Call non stop. I made the mistake of calling back and asking to be put on the do not call list. Now they call me 4 times a day. It seems being on a national do not call list is as much of a joke to these people.
And again they call with a final notice about my warranty. This time, after I answered the questions correctly, the robocaller transferred me to another bot. That's new. Thought she was live... They're getting better at this. I'll try again tomorrow with their next final notice.
