We cannot block any number from calling you. You must block it yourself. Call blocking devices (or app for your cell phone)-are available online (or at the app store for your cell) and start around $45. http://800notes.com/nb/search?q=call+blockers
Same thing happening here too. Caller ID says wireless caller. I block their numbers from my phone but these people just change their numbers frequently. I don't even answer anymore,
