DONT EVEN TRY IT!!!! SCAM

Ive been looking for an app that allows me to screen, block, do not disturb etc on my phone and thought this was the answer. However you cant even try this app, I downloaded it and when I opened it I was instructed to call *777 on my iphone (yeah right!)
So Ive deleted the app and will tell everyone I know not to bother its a scam if you ask me, apple should check out these apps before allowing them on their site!
I GIVE THIS APP ZERO STARS!! but I had to give it one to post my review (another stupid thing!!!)
