Great app but found a bug

I have been playing this game for some time and I found a bug where I watched a video to get a free continue and when I pressed the continue for free button once the jade charge was 0 it still charged me 10 jade or 3 jade and I started off with 177 and now I have 8 jade
Please fix this and reimburse me. Thanks
