I've been pestered by a certain individual via calls and texts lately and it's getting a bit irritating. I want to block him off my phone completely but I don't want to change my number. I'm using GO SMS Pro and there's an option to block texts of selected individuals. But when it comes to calls, there's no option to block a single person only when I go to "Settings". Is there an app that could block a selected phone number only? If so, could you give me the details? Your help is much appreciated.
