Wouldn't it be wonderful if there were a website you could just visit and tell the owner to block a telephone number for time and eternity, 'till the stars burn out, etc. etc. Unfortunately, M. Hui, no one at 800 notes, nor any other site that I'm aware of, can block numbers for you. You must do that yourself. Get a call blocker for your land line and download a call blocking app for your cell. Some phone, both land line and cellular, have a built-in feature that will block unwanted calls. So take charge. Do it yourself.
