Doesn’t work – BlackList: caller ID & blocker Review

I’m unable to use the add number feature, and even when I added the number as a contact the app only loaded some of my contacts. Waste of time and space. Besides, if I was trying to block single calls instead of a range of robo calls, I’d use the built in feature on iOS instead of some crap app.
