Clearstone Windows or Windows Clearest. This telemarketer has been active for years; to the best of my knowledge no enforcement action has been taken against them despite clear disregard for the do-not-call list.
They call my work number all the time. I finally picked up and they asked if I wanted my windows cleaned. I don't have any windows in my office because I'm in the basement.
I was receiving calls from this company every day and they didn't leave a message. Finally I called it back and it's a window washing company. I asked them to remove me from their list. They were nice and apologized and said that they would take me off right away. I'll update if they don't remove me.
