I keep getting the same thing Duct Cleaning Service and when I tell them to stop calling they hang up..... They call here at least twice a week.... Anyone know how to get them to stop calling?

phone call is from a duct cleaning service that is offering a promotion, so they say! very rude and hung up when told them I wasn't interested. Called the number back that they called from and it is not in service told to check the number?..

Probably another political call; no message left...........
