Screaming Chicken

The IP blocker part of the app doesn't prevent anything. Blocked IP addresses are still attempting to make purchases. There is no customer service or tech support response. It says on their chat it will take up to 30 minutes to get a response; I waited for over an hour with no response.

Had a small issue and they were able to fix it quickly. Overall I've been very happy with the app, I've been using it for about 2 months now.
