Brujas Guía de Viaje con Mapas Offline

I was trying the application and a pop up came up every second asking me to buy the application. I was trying to exit and I press de home button but the app is designated to make me buy the application and by the moment I click the home button it automatically accept the payment for the complete application. This is a scam! As it is designed to make the user buy the application by inducing the user to the error.
