There are many reasons why your order was canceled. Down below we have some of those reason why your order might have been canceled.
The merchant is too busy to take new orders.
The merchant cannot accept payments due to an equipment malfunction.
The merchant is cash-only. Postmates cannot place orders at cash-only merchants.
If your order should be canceled, Postmates will either send you a text message, email, or push notification explaining the reason for the cancellation. Postmates will also temporarily deactivate the merchant on the platform until the issue is fixed to prevent other customers from running into the same issue.
