You may have received the same order twice only minutes apart, same value, same customer.
The cause is generated by a bank or gateway communication error. When an
order is placed and payment is made through a real-time credit card
option, our shopping cart waits for a signal to return from the bank to
let the cart know if payment is approved or declined.
E.g. During the processing of a transaction, if the bank is busy and
doesn't send this signal, the cart must decline the order after a short
while. In this case, a customer will go back a page and attempt to
purchase again, this time the order is approved.
10mins later the
bank sends a signal saying payment for first order was approved so it
updates that order ID to approved and you now have the same order paid
twice, only moments apart.
Some banks are better than others with communication or charging que's.
We're happy to discuss your options if you would like to email or call a
