Cancelled flight after hour on tarmac and refused refund 15/3 auckland New Plymouth

After 45 mins on phone and two online chats three emails to exec unanswered Still out of pocket $408 for flight cancelled. Although terms say flights will be transferred or reimbursed there seems to be no credibility in offer. Had customer services contact me asking if I’d recommend Jetstar and replied no. They sent email asking for patience with fixing delays and ignored responses.
Not worth conisodering as a flight option
