I've been getting a lot of these type of calls too. When they ask me to press 1 to speak to a rep I do. When the rep picks up I play a recording of the Three Stooges singing "Hello, hello, Helloooo" and follow it with Curley saying "Woo, woo, woo, woo". I also have a recording of an operator asking them to make a 25 cent deposit and dial again. I don't know what they think of that one considering that they've probably never used a pay phone. Since they rudely hang up on me I never get a chance to ask them.
