Apple/iTunes card $ not accepted?,

Enjoyed the game; so I purchase an iTunes card . Deposit said cash into Apple Store for hay day diamonds . Only to have my $ refused?! The game tells me insufficient funds-does not accept my iTunes payment through Apple Store. Not impressed, bc I love the game enough to actually put real $ down on it. Unfortunately the game doesnt think that way of payment is good enough? Confused and irritated!
