Have you tried making a complaint or taking the matter further? The link below has details on how to do this.
I have been using Optus for so many years now. I was away for two weeks for holidays in Europe. There was bulk charge for over 850 mb in one of the country.
I have tried live chat, phone calls. All the staffs are just pushing me to acknowledge the bill and get into a payment plan. This is disappointing.
I have been told that my apps would have updated itself or when the wifi is weak my phone would have connected to the mobile date. Poor excuses when I clearly know I didn’t use that much of data for anything.
Hi @Shana14 - did you receive SMS alerts advising of the charges when you were overseas? If you can send through a PM with your account details - full name, date of birth and mobile number, we can take a look into this from our end and provide more insight.
