Please submit a ticket from the shift in question directly through the app. You can do so by navigating to the Profile tab, then click the gear in the upper right hand corner. Once on the account and settings page, click Payments, scroll to the shift or shop in question and click "Need Help with this Payment?" to submit a ticket.
For general payment questions, such as how long does it take to process pay, we ask that you please review our help center section on payments here before sending an email to our specialists.
