Voucher Credit

I have a $22 credit left on a Jetstar $100 voucher but their system will not allow this to be used despite their blurb on the phone while waiting endlessly ,only to be told to ring anothr number which I have alresdy spoken to & they said they dont controll the vouchers useage so call another number..same as previously..Absolute rubbish & you cant email customer care as it just bounces back with."thank you for contacting customer care,your email did not reach us" An absolute disgrace..
