No time limit version and locked levels

I have this game on my computer and I love it. (Well, it varies slightly and is called Mad Caps. ). The most fun rounds are when youre racing the clock, otherwise theres no challenge. And the hardest levels are locked with no explanation (I can find) to explain how to unlock them. All I can find is a link to a store that sells thousands of coins for $1, but I dont know what I need the coins for. The customer service button links me to a non-existent page. I bought the game and I dont think I should have to pay more money to play all levels of the game.
