You can block it through the phone but it just sends it straight to voicemail. If it's a private number then you really can't block it.
Depending on your cell phone carrier you might have some options. Let them know that you are receiving harassing calls from a private number and you should be able to get your number changed at no cost. Also see if they can block the number for you but most cell phone providers are not able to.
