I just had a terrible experience buying my ticket through gotogate(https://au.gotogate.com/). I bought my overseas ticket on 6/11/21 for $760, then suddenly just today(9/11/21) I've received an issue for a refund for my ticket without any explanation.
I tried to call their customer service which I have to wait for more than 1 hour to ask what was the reason of the cancellation. He first said that my flight is cancelled, then I told him that gotogate is still selling the exact same flight but now its $1250 so I'm pretty sure that the flight is not cancelled. So I asked him again the reason for the cancellation and he hung up on me. I tried to call again for the 2nd time and have waited for almost 2 hours now with no one answering.
I'm not even sure if I will be getting my refund considering how bad the reviews are(https://www.productreview.com.au/listings/go-to-gate)
I'm planing to make a complaint to ACCC and hope my experience will help anyone to reconsider booking a flight ticket through gotogate.
Just pay the difference otherwise just move on.
