The initial charge was most likely a pre-authorisation @vKiiMBOv. A pre-authorisation is a temporary hold on money in your account which is generally the balance of an item or service you have ordered. This is not a charge and the money does not leave your account, it is just the bank and service provider ensuring that the money is there to cover the order. If you look back over your invoices from your credit card company you will no doubt see that while a certain amount of money was earmarked it was never actually taken from the account. 

If after this the order is not going through then it would mean that the bank or card issuer is declining it. The best thing to do is to reach out to your bank or card issuer and check for any issues.
