Refund Dispute

I requested a refund for a purchase I made from Boom Beach. The app was not working correctly and though I tried to purchase the item in the game four times in a row, none of the purchases completed and I did not receive the item. Then later, I found that I was charged four times for the non-purchase, even though the item was listed as only available once. When I tried to dispute the charge, it was denied, which is unbelievable, considering that anyone looking at the record could the four charges were placed right at the same time. I am frustrated because SuperCell does not have any direct contact info, so I can't dispute the charges with them and Apple does not offer the opportunity to talk to a live person to discuss why they would not give me a refund. It is most annoying to be charged four times and receive nothing and have no one to talk to about the issue.
