Bests & Worsts Reviews from Amazon

I bought the 1.99 purchase to unlock all the cars and themes and now they are NOT available anymore and remain LOCKED so when I tried to purchase them again it said I ALREADY OWN IT and won't let me purchase it YET IT REMAINS LOCKED AND INACCESSIBLE. My kids LOVE this game but they get only one star for taking my money AND taking away my purchase and THEY WILL NOT RESTORE MY PURCHASE. They got a one star bc I couldn't go lower.
