Just make an appointment for duct cleaning and when they show up say your not interested and shut the door on them.

These idiots even call on Family Day!

When you get these calls. Just answer, but don't say a thing, and they just hang up with out saying anything. They give up and stop calling after a while.

Almost getting a call for air duct cleaning service every week. Today, after the caller indicated that they offer air duct cleaning service and I said I don't need that, he hang up on me right away without even goodbye or thank you.. It is so impolite and rude.

So peed off
