There could be two reasons why your order has been canceled online:
Our online system will automatically cancel an order after 3 days if payment is not received.
Once your order has been placed please make sure to email us your proof of payment at: info@casaminers.com
If a payment is made through Coinbase Commerce, please make sure to send the exact amount as stated on the invoice. If the incorrect value is sent your order will automatically cancel. If you receive this notification do not worry.
Please contact us and we will manually resolve this for you and replace the order on your account.
