Salesmen ringing away

People trying to sell you something that knock hard on your door or ring the bell a few times until you answer.

Still trying to sell

Why call again and ask if someone is interested if they already said they are not interested?

Salesmen calling at dinner

It always seems near dinner time or later that someone calls. Worse is on Sunday when you don't want anyone calling.

Salesmen calling late

Calls late at night are annoying.
