Uncontactable Jetstar

Great customer service, I made a booking, gave my credit card details and hit purchase. It came up showing that I had paid but for some reason still owed the credit card booking fee, tried to pay the $7 but again came up showing it was still owing. I have a confirmation number but booking wasn't finalised as far as I know. Tried to contact Jetstar to confirm the status of the booking and wether I had been debited but the only number you are given is 131538, no options just a message telling you to try again. I did several times, obviously Jetstar don't want to be contacted by their customers, we may need some service, wouldn't that be an inconvenience. Next booking will be with Virgin, bye Jetstar.
