I made a complaint to Jetstar nearly 4 weeks ago after having a poor experience including flight cancellations, additional costs and not being able to speak to an Australian employee. I attempted to resolve the dispute by phone however unable to speak to an Australian employee, via like chat with ask jess but still unable to speak with an Australian, thought I would give twitter a shot and no luck there... finally got a response when I added a manager through linkedin..
I followed proper protocol by escalating the complaint to ACA which is funded by the airlines and by no surprise it resulted in the same outcome.
I currently have a registered dispute with The Office of Fair Trading and had quite a pleasant call from them today. I would encourage anyone on here who has a complaint that you weren't satisfied with Jetstars response to register their dispute on the link below. it's recorded online and while it takes 5-10 minutes to lodge the dispute it will hopefully gain traction as Jetstars response to complaints are appalling with majority not every bothering to escalate it.
