Telemarketers on my cell phone?

So I get a call today with a recording asking me to extend my car warranty......

I press number 2 to speak to an operater because we are on the do not call list.

Him: Hello would you like to extend your car warranty today?

Me: No, I would like to know what company this is please.

Him: click - yep he hung right up on me.

I need caller ID.
