My 6 year old son loves to play Cartoon Wars on my Android. I recently noticed several charges to Google Wallet related to enhancements he purchased for the game. I normally use it to purchase books from Play Books. He is 6 and always asks before he downloads anything, but somehow he ended up purchasing about 300.00 or so worth of game enhancements within a few hours.
I saw the notification emails and desperately tried to figure out how to get a refund. I was fearful that since I had failed to set up a pin to be used prior to purchases, I would have no recourse.
I contacted support via the following link.

Someone from support called within seconds. I must note I made this call around 1:30 am in the morning. They were alert, polite and patient. My son has purchased 21 different items within a 2 hour period. He reminded me how to create a pin number so my son will not be able to make purchase without my approval. He refunded all 21 purchases. Within minutes I received email confirmation of the refunds. I was completely surprised at how friendly and efficient the service was. I really expected to be told the charges would stand or at the least I expected a long drawn out effort to get a refund. The fact that the charges were made were a mistake on my part, I should have configured Google Wallet to require a pin number. I would recommend using Google Wallet, I have had a great experience with it.
