Did you place an order with us and does it show up as cancelled on your account? There are two main reasons why orders are cancelled:
If you did not make a payment for your order, the system will cancel your order after a while. Always double check to make sure you made a succesful payment.
It's also possible that you placed two identical orders. In that case, the unpaid order is cancelled. Please double check to see if you received two order confirmations or see two identical orders in your account.
Is your order cancelled and none of the above applies? Please contact our customer service to look into it.
