I've bought over the Kindle coins for a game. The purchase is confirmed and the sum debited from the account. However, the amount appears neither in the game nor the written somewhere else well. I had since complained by phone from Amazon. However, on the hotline will be put off and promised contact via the Service Team by email. Only - there is no answer and one is left with the problem alone. Has happened for the second time in succession me now. Will definitely leave it alone.
