courtesy call 

A sugarcoated term used by telemarketers which really means sales call. One of the most deceitful and misleading phrases ever since there is nothing courteous about it.

Telemarketer: Hello, may I speak to Mr. Smith? Hello. This is a courtesy call from Talk America which is inviting you to switch to our service. You'll pay only 10 cents a minute and you get the first 100 minutes free.

Mr. Smith: No thank you.

Telemarketer: Well, sir you get blah blah blah.........
