Calling about duct cleaning

Nasty woman with the thickest southern accent that I have ever heard calling about Air Duct Cleaning.

I asked her how big her bosom is, she reprimanded me and told me that I could say "not interested."

I told her that I didn't need phone etiquette lessons when I am on the Do Not Call List, thank you very muich.

She hung up on me.

This is not an Air Duct Cleaning Co. They are Private Investigators from Greensboro NC. They are very high strung people. Be careful when talking to them. Also record the conversation if at all possible.
