Expensive purchases disappeared!

My kid likes the app. I purchased a year for her - at $10, which isnt a lot, but it is when you can buy several other great apps for that price. She told me months later that it didnt work anymore, so I thought the year must have been up. (I cant remember when I buy what.). The app wouldnt restore purchase, so I purchased again. That was yesterday. Today the app didnt work again. Now Ive emailed them and Im getting no help.
