If your card said it was used but you didn't receive your bitcoin then we have successfully sent you your bitcoin. Please allow up to 20 minutes for your transactions to show up in your wallet. You can check the status of the transaction by viewing your bitcoin address on the blockchain here: https://coin.cz/ -> Simply paste your bitcoin address in the search field. You will see a number of "confirmations." Usually it takes 3 confirmations for your coins to show up in your wallet.
If you still don't see your transaction after 20 minutes then there was an error on our end getting your coins out. Rest assured, your funds are safe with us. We will need to manually push out your transaction. Please email us at email@example.com with the details of your transaction so we can push it out.
