Not working, and support not replying email

I am using iPhone 4 and iOS 5.1. Downloaded this app. On the web site, it says free 90 days Premium trial, but doesnt work in the app store. Since it is only 1.99 for a month and it looks promising, I decided to give a try. But the features are not working! The SOS doesnt send SMS message. Also, I didnt get SMS for Follow me as well ... I cant believe it.
