If you did not receive a receipt and an order number via e-mail, then we did not charge you and will not be charging you or accepting any funds from your credit card company.
It is possible that your bank is holding the funds until they confirm that we are not going to accept any payment for the failed order(s). Typically the banks will hold these funds for 7-10 business days. You will need to speak to the bank directly if you would like those funds released.
