Worst customer experience i ever had!

I called Jetstar Asia call centre on 06 July around 7pm and i have to wait for 25mins before i can get to speak to a call agent. Waiting time aside, a female staff who talked with a funny slang which probably only people of her same nationality can understand her, rudely disconnected my line. I was already very frustrated on not being able to use my Jetstar voucher online but she wasn't listening to me and kept going on to tell me a T&C which i cant see in my voucher as she insisted i can't use this voucher of mine to the destination i want! But 1-2 weeks ago, i did call to enquire also on the usage of the voucher. Another female staff told me there's no restriction on how and where i can use my voucher.

Feeling hard done by i called again straight away after that staff cut off my line and of course i got to wait for another 20mins and this time i demanded to speak to a manager. To my horror, this so called "Team Leader/Manager" by the name of West is just as hopeless. He has the worst communication skills for someone of his position i have ever come across. Not only is he not addressing the problem, he even accused me of shouting at him when he can't hear me clearly to start with! I was already on the verge of begging him to solve the online booking problem so that i can book myself but he was "kind" enough for wanting to perform the booking for me through the phone but he wanted to charge me at a higher rate by claiming that phone booking costs more. It's only when i protested then he relented to charge me as per the price shown online. When i reminded him about my complaint on the previous staff, he didn't bother to act on it, instead he wants me to submit it online and he tried to resolve it by saying will send me a $50 voucher! Which of course it didn't happen.

Question to Jetstar Asia's top brass, why does their staff keep giving varying replies? Why are the call centre staff so hopeless by directing customer to other channels to lodge a complaint? Why do the call centre staff insists the Jetstar vouchers are limited to selected destinations when i don't see this clause in the T&C? I wasted close to 2hours calling the call centre to resolve a problem but, i got more problems during the process. Worst call centre ever? Definitely.

Subsequently on 16 July, Martin from Customer Care called me and i told him my issues and problems that i'm facing. He promised to call me back on 19 July but failed to do so. He called me on 20 July when i wasn't free, yet he didn't have the courtesy to apologise for failing to call me on the previous day. Even when i questioned him, he had the cheek to reply that he wasn't available to call me (but is it my problem?). Never mind, again promised to call me on 23 July but failed to do so. I'm utterly sick and tired with Jetstar's way of managing customers, it's a total disgrace. To think i've been supporting Jetstar faithfully for past 2-3years.
