So I'm having a hard time with a pay adjustment and I'm wondering if anyone has had the same issue.

Left the gate in CLT goin to GSP. Thunderstorm moved over the field. It cleared but dispatch had us return to the gate and cancel. Submitted my pay adjustment for the cancelled GSP-CLT leg and it got denied. Flight support states that the return to gate was 1hr 45min and the credit for CLT-GSP-CLT was only 1hr and 35 min therefore no pay adjustment is due. Currently arguing it with them but if anyone has submitted for something similar and it got approved and you still have the email, could you PM me? Thanks.
