Is an order late or missing? Do you need to reschedule it?
EasyRoutes is just the software used by merchants to power deliveries. If you require support for an order you have made, you will want to get in touch with the store from whom you made your purchase.
You can find the contact information for your store in the tracking page, or by reviewing your Shopify order status directly (e.g. visit "View Order Status" if you are viewing the tracking page).
