I bought an Item and it was never delivered
This may be because of several reasons:
There was an issue with Credit Card Authorization and the order was rejected.
Please double check your credit card account and see if you were charged for the purchase. Also check if Google Play store has all the required data to bill you for the item.
There is not enough funds on your card.
The purchase was not delivered because you have reached the limit on your credit card. Please try to make a purchase after you refill your card.
