Just called my home phone, which is listed on the Do Not Call Registry, about being a restaurant owner. I know there are days that I feel that I'm a restaurant, but...! Reporting it to the Do Not Call Registry.
Posts like yours just show everyone your level of ignorance about how much you think you know but don't.
Just for your information, the Do Not Call list does work. All the legitimate companies who follow the law don't call you anymore.
So who's calling?
Ninety nine percent are scammers, con men, and ripoff artist who want to separate you from your money. The other one percent are individuals and companies who think they are too small for the FTC, who oversees the list, to bother with.
Would you trust an alarm company, who is breaking the law by calling you, to protect you and your property? Give you a "free" alarm system just for putting a sign in your yard? Really? Like the guy on the phone is working for free and the guy who comes out to install it (if he even shows up) is working for free. Oh yes! Let's not forget that the parts for the alarm are free also.
My response to that is the same as it is to your post. HAHAHAHAHA!
