can't use bought bricks

i finally have level 1568 where i want it had to use some bricks so i could complete well that's not working can't use the bricks that i have already purchased this is just not right like i have mention i previous post been trying to get past level 1568 for 3 days now with over 60+ trys and finally get it to where i don't need to use a lot of my bricks for extra moves but that is not so this is just not right at all this game is expensive enough without these kind of things and also i'm hearing from other people that they don't seem to be having the troubles that i'm having getting through levels i have spent enough for this app i would like to get a refund for the 230 bricks i have now so i can just walk away
