If your customer does not agree with your invoicing for an appointment he/she has the option to file a case directly through his/her profile. If a customer does this you will automatically receive an email and an app notification.
You can find the cases your customer has filed in your user account. Please go to "More" and click on "Service-Portal"
Here you can view your past and present cases and the status of your present case. You have the option to either refund your customer (“Refund customer now”) or reject the claimed refund (“Reject refund").
