App doesn't work after registration – Abakada - Learn the Tagalog Alphabet Review

After I signed up to avail of other activities for my child (numbers, colors, etc.), the activities won't open. It was a complete disappointment. Please remove this app from the App Store if it doesn't deliver what it says on the app description.
