At 1st I thought it was great but when I uninstalled it, it was still blocking calls. I followed EVERY step that customer service had given me and STILL it blocks calls and tells people that I "won't bother checking my messages anyways" and hangs up. I've researched this online and apparently this is a HUGE issue that has yet to be resolved among not just Android phones but also Apple. Customer service is no help because they just keep referring you back to the same exact steps that do not work.
