Many times the reason is that the commuter order typically failed to load onto the card. The top reasons this happens are a) an invalid Card Reference ID number is provided, b) the card has a negative balance, or c) the autoload feature has been activated.
To rectify any one of the above issues, please log into your commuter account and either update your Card Reference ID number, upload funds to change your negative balance status, or deactivate the autoload feature.
