It does not download!

I have a MacBook Pro 13 inch. This app is not downloading on my Macbook Pro. It downloades for some time and then it says error. So then I have to download the whole app again. It is a lot of money gone to waste. If Lego could solve this problem or refund the money, I would be happy. If no action is done I am going to court. Please fix this as soon as possible. Do not buy, it does not download. It is a waste of money!
