telemarketers

Telemarkets call everyday for me this is nothing new. Usually they are foreign and I can't understand them or I instantly recognize who they are and hang up. A few days ago I got a call and listened for a little while longer than usual for who knows what reason but I think it paid off.

Caller:"Hello, is this K?"
Me:"Yeah."
Caller:"My name is Jammica and I'm with Publisher Clearing House."
Me:"Go on."
Caller:"I am calling to tell you that you have definitely won some money that will be awarded to you as some date next year. But I need to ask you some questions."
Me:"Shoot."
Caller:"Do you carry a Visa, Mastercard or Discover card?"
Me:"Yes."
Caller:"Which one of those companies offers you you the best service?"
Me:"I carry a card, but I don't really use it so I can't answer your question."
Caller:"Um, what?"
Me:"Well like I said before, I carry a card, but I don't really use it so I can't answer your question."
Caller: "..." *click*

Yeah, so she hung up on me. Was it something I said? I thought I was being polite.
