If it appears that the money has already been taken from your account but you did not get an order confirmation or the order didn't go through then don't worry, you haven't actually been billed (even though it looks like money has been taken out). You may be experiencing a 'shadow' of your transaction, or 'amount pending'.
In these cases, your bank or card issuer has allocated funds from your account to pay for your order with us, but when the transaction fails we do not receive the money.
Since the transaction failed, this amount will not be taken from your account and will be reversed by your bank or card issuer. The transaction will reverse in 1-5 working days. You should see on your bank statement that these amounts are pending and subject to approval and may not be charged.
This situation only comes into play due to AVS (Address Verification System) or CVV (3 digits on back of card) security checks to help protect against fraudulent transactions. Most likely, the postcode / zip code you entered did not match the bank card details that were used to make the transaction. This process protects both us and the customer from fraud.
Unfortunately, we do not have the authority to cancel this pending amount and so we recommend contacting your card issuer directly if you have any further queries or want reassurance.
In short:
The pending transaction you're seeing is only an authorisation, and will automatically reverse shortly.
To prevent this from happening again, please make sure you enter the correct postcode / zip code as your bank card or use another payment method (such as Paypal).
