When you enter your payment details, you will see a nice green tick on the Stripe screen. This tick does not mean your transaction has been authorised, but that you have entered your name, an address, the 16 digit card number, expiry date and CVV correctly.
Our system then contacts your bank to process the transaction. Your bank then releases the funds into a 'pending state', waiting for collection.
If your payment has failed due to an address error, we will not collect the funds and they will return to your account within 24 hours, when your bank realises the funds will not be retrieved.
