If you believe you were paid an incorrect amount, it could be a simple mistake with an easy fix. You’ll need to contact your hiring manager to explain the discrepancy, from there you and your hiring manager can discuss the next steps of your payment.
You can always send your hiring manager a message in the Jobble Chat. If you prefer to reach your hiring manager directly, you can find their contact information in your acceptance email titled: “You're Hired! Your Application Has Been Accepted.”
