This number has called me at least 13 times that I’ve reported to the Do Not Call list complaint site. The voice mail they leave (in spite of being blocked) talks about duct cleaning and a special to clean every vent in my home. I have never been able to reach a real person when I call the number back (since blocking it doesn’t work). The phone is registered to a Richard Goff, located on Rocky Ford Road in Grandview, Washington. Since I cannot determine the actual company name, or even if Mr. Goff is aware that the number is being used in this manner, hopefully you can help. I reported this number before, but received no help because I couldn’t provide a company name. When the robocall doesn’t MENTION a company, and the number they call from doesn’t either, how the heck am I supposed to know?
