Why is Jetstar still in business?

Tried to contact Jetstar all day to confirm a booking I had paid for - before being told my session was ended. The flight is tomorrow — normally! Tried phone, email, customer care service... again and again and fucking agin! I'll just front up at the airport tomorrow and hope for the best. First and LAST TIME I will ever fly Jetstar. Just can't believe the incompetence, total disregard and lack of respect for their clientele. DON'T fly with this company. Unbelievable! But can't understand how they manage to remain in business.
