payment blocks

What is the matter with payments via Credit card? I was playing level 6935 (difficult level). The first attembt I almost reached the end. Needed 5 extra try's, bought 19 goldbars to reach the level with 1 strike of the lolly hammer. I payed but then again the game blocks. The amount of money is payed. I can see that on my bank account. So please hand me over to level 6936 and take 1 lolly. This problem occurs already many times this week.
