Full version not available

I purchased the full version of this app about a month ago and was able to get the entire alphabet but now when my daughter plays she no longer has access to the other letters, only level 1! It keeps asking me if I want to purchase the full version but I already did and when I hit yes, it just sends me back to the App Store where I cant purchase the full version again because I already did! This is a rip-off and I want my money back.
