terrible direct deposit system

Hi guys,
I wanna share a very bad experience about Jetstar airline.
The story begin 3 weeks ago.

23rd July, I booked the flight from Melbourne-Sydney (round trip) on 13th - 16th Aug on the website and paid an airfare via direct deposit at AUD$138.00.

25th July, I called Jetstar to confirm my itinerary. Staff said they haven't get any money.

26th July, Calling again and they said the same thing.

27th July, I called again. The staff said send the document to proof that my money gone through ur account. Then I called my bank and she said 'the money gone through their account already since 25th'. So, I fax them my documents.

28th July, I called again to confirm that they already receive my paper. They said I have to wait for 3 days.

1st Aug, I got an email from Jetstar that tell me confirm that they got my documents and allow them 15days to operate.

3th Aug, I called them to wanna know the process. The staff was very nice. She followed her supervisor and asked to finance department. I had to wait on phone in total 1 hour. However, she said the admin still on process and the outcome will be on 10th Aug whether u get a flight or refund. And reckon me that if i really wanna go this flight, it's much better if u book another reservation via credit card to make sure i can fly there.
So, I booked it and i paid by credit card this time 'the price was $200'. I got confirmation withing only 2 mins. And I told her that I need Jetstar to work on the first flight for first priority. I'll keep 2nd flight for the last minute. After talking to her, I will wait for 10th Aug.

10th Aug (today) 1pm, I called Jetstar at noon talk to the staff and the let me wait for 20 mins and tell me that they will call me back within maximum 2 hours but no calling.

10th Aug, 5pm, I called again, and i have to repeat everything of the problem again. finally, the staff let me talk with the supervisor. She explained to me everything about the process, step-by-step. I still complain because everything is not really make any sense at all. I BOOK AT CHEAPER PRICE AND WAIT FOR 3 WEEKS BUT I HAVE TO FLY WITH ANOTHER FLIGHT THAT IS MORE COST!!!!

During that time, she always say the same shit thing; that is the rule, bla bla bla. we can't do anymore, bla bla bla. and finally she said u have to option. First cancel all flight and u cannot fly or cancel first flight and u can fly 2nd flight. or u can book a new one. I said "Hell NO" more expensive obviously.

it's not fair for customer. this company doesn't know anything about "Service" at all.

Thanks for ur reading.
