it's a good game but, bought a package for a 5 to 6 star upgrade package but, I read description as use exp to level up 5 to 6 star, so I used it as xp and then it when I hit level 20 it told me I had to use it as an upgrade card. Instructions were unclear and contacted support but, they just told me I can't repurchase the package or even get refunded for improper wording. The game is good but, support wasn't that good on the game.
