Monsters wont heal

Game is awesome its the closest thing to Pokemon on the App Store, but my only issue is I cant get my monsters to heal Ive tried resting and going to the ranch multiple times but its been a week and they wont heal. Also I cant purchase anything in the game for some reason. If somebody could help that would be awesome. Overall great game just minor bugs from my experience.
