iTunes refund denied
My 11 year old son took advantage of me being out of the country and bought 17 times gems for a soccer game. $45 dollars each! As soon as I noticed I requested a refund for the transactions using the process. My reason was because he did that purchase without proper permission. They denied the request for 16 and refunded it once. I re issued the request explaining the situation but iTunes denied it again and now I have no way to re request a refund. Can someone help me understanding what can be done? I can’t pay 700 usd for gems in a soccer game! Please help
