Once the prices have been set up, the item prices cannot be changed according to our Terms & Conditions.
If there is a mistake on the menu, please immediately mark this item as unavailable to prevent new order from coming in until the issue has been resolved.
For that please refer to our Marking an Item Out of Stock article that explains how to do this.
Then please reach out to our Support team to report pricing error.
Note: Once the restaurant has accepted the order, the price cannot be modified.
