Pro key does not work any longer besides been paid TWICE!!!

When opening KLWP, I noticed it wasn't Pro any more, I've checked the Pro key was installed... Reopened it, reinstalled, still NOTHING... In the FAQ was Said to rebuy in-app, and ANYTHING WILL BE CHARGED, so I did... Nota only I was charged AGAIN!!! BUT STILL NOT PRO... NOW I CAN'T MAKE A BLOODY RATHER URGENT PAYMENT, BECAUSE THE BLOODY APP STOLE MONEY FROM THE CARD, AND EVEN SO, I'M STILL NOT PRO!!!!!... Bollocks!

Same problem I'm having with KWGT. Wonder if posting a bad review on Google Play gets a faster resolution.
