Translink has revealed the millions of users of its tap and go system are subject to strict refund limitations.
The new limitations prevent passengers from disputing more than one fare per week, or two fares per month, regardless of the legitimacy of their claim.
No refunds are awarded for human error, such as forgetting to tap off.
The revelation comes as part of an ongoing investigation into the state transport systems which have seen NSW company Opal come under fire for its 3 disputes per year policy.
