It takes my money the it shows an error message then goes back to that screen and no gold block to purchase so only choice you have is to give up this has happened 6 times but it already took my money but cant go anywhere have no choice but to give up. Not cool at all.
Could you let me know what level this is and also your Game ID so I can take a closer loo at this? If you play on Facebook check here and on mobile like this.
