F off stop calling me. I don't want my ducts cleaned!

they just called again, the called last week and I asked them not to call, I guess they just do not listen, I am buying a whistle and the next time they call, I am going to answer and blow the whistle as hard as I can in their ears. It won't hurt them because as we can see they can't hear anyway.

This number is Air Duct Cleaning Services. They call people over and over, week after week. They won't stop.Next time i will have them drive here and then not be home. I will take their license number and call the authorities.
