Called. Left no message.

I just got a call, he wanted to sell me credit card processing. He said he could guarantee that I'll only pay 0.05%, I told him no, I pay zero. He said, "when did that happen?"  I told him that was what my company agreed to. He sucked his teeth at me, sad, "yeah, right," and hung up on me.

I'd like to block these numbers, how do I do that?
