This could be for several reasons such as the inputting of the wrong email address or technical issues where the system has timed out before your order had time to reach our ordering system.
If this is the case you may see a pending authorisation from us on your bank or PayPal account. As this is only a request we will never take the monies from your account and they should drop off back into your available balance after a couple of days.
This is different for PayPal orders as this can take up to 30 days. More about this can be read here.
So that we can look into this for you just get in touch.
