Is there any way to block a caller? I have been getting calls from some international number, 011 0012063373269, EVERY morning for the last month. It has become very very annoying. I ignore the call. Easy enough. I know I could add a silent ringtone, but I want the call to just be dropped or rejected. I cannot believe in this day and age that option is not available. I looked through the #block and blacklist apps in the app store for iPhone and the apps are all a joke. They don't BLOCK any numbers. AT&T, really? No way to to reject a call from this annoying robo caller?
