Goggle play charged me $**.** for a package purchase on *ball game app. What happened is...*I was playing pool continuing game after game and I was use to the routine of returning to the game choice window when in the middle of my finger press a package for purchase window popped up and I ACCIDENTLY hit it. I realized what happened so I was very alert not to touch anything so I simply backed out. That should of been the end of it. It never said thank you for your purchase or anything so I DID NOT REALISE the purchase. I left the game right after that. When I returned to the game I did not notice my play amount increase. I already knew I had a few thousand to play with and I hardly ever go over a ten thousand bet game until I went to move the high bid games aside and the only way to do this is to press and slide each option till I reach my desired bidding amount but when I tried to slide away from high bid game it instantly went right into taking out a whopping hundred thousand I didn't even know I had. Well of coarse I played that one game because I didn't want to waiste it. That's when I realized that Google made to his purchase for me. I quickly uninstalled it and I have not played *ball since. I am now in fear of all your games that have pop up purchase packages on them. I've purchased many gaming packages from you all but I have never purchased any game packages over $**.**. EVER and even that amount is very rare for me. I am on a fixed income and cannot afford $**.**. please give me back my money. You can pro-rate the amount I didn't mean to use on *ball. To sum it up goggle play made this purchase for me because I know for a fact that I did not press on that purchase window what so ever. I seen it and I avoided it by backing out. I was afraid to even push the cancel button for this very reason. Yet here we are.
