I'm not sure if your carrier provides a way to block a number, but I know if you log on your account for Verizon, you can block up to five phone numbers from calling you, and I believe another five emails. You might want to take a quick look on your online account, and see if this option is given. Also, calling customer service may help you out. Although I'm not completely sure, I don't think there would be a way to do it with just your phone; it would have to be stopped with the carrier.
