I’ve found a match of a vendor and customer where the payment is showing in both their paypal accounts. So I’ve marked that order in wp-admin as processing, so that it would appear in the orders tab in the vendor dashboard. I then manually sent them both the order confirmation email (by amending the cancelled order email).
But the other customers say they didn’t cancel and the payment has been taken from their paypal – but the vendor hasn’t received in their paypal account.
Panicing muchly!
