www.spytoapp.com review: The app stopped to work and online agents as well

I downloaded the app from the company www.spytoapp.com. I wanted to know what my daughter was doing and where she spent her time. I used the app within 2 weeks and suddenly the icon popped up and showed that my trial was over. I didn’t understand what has happened. Also I tried to ask the online chat agents, but they kept silence. Maybe someone knows what has happened, please help me then.
