I have two customers with the same name in my system, and I accidentally added the wrong one and completed the transaction. This meant that the wrong customer got sent the receipt, and the real customer didn't get one. It also meant that the wrong customer got the Marsello loyalty points and the real customer didn't get any. I can update Marsello points manually, but how do I fix the record in my system of which customer made the purchase, and send the receipt to the correct customer? I can't cancel the order because it has already been completed, and I don't want to refund it. I use Shopify POS and web, and they are connected, if that's relevant.
