I can see that the system canceled the order because it detected that no delivery person was available to pick up the order on the merchant area.
I understand the experience was frustrating, however, we are unable to provide higher compensation for this concern. Since you were not charged for this order and also the money that you were supposed to use to pay for the order will not be taken out of your card it will be back automatically to your account.
I understand that you wanted the 20% credits since this order has already been canceled due to the system detected that no delivery person was available to pick up the order on the merchant area. We can no longer give you the 20% credits as you were not confirming a while ago before the order has already been canceled. Thanks for understanding.
