I went abroad last month, and received a big bill - about $600 for overseas charges. My issue was - I barely used the internet as I was conscious of this!! On the first day I ended up having to make some work phone calls and check stuff on the internet without realising wifi wasn't on, I am fine to pay that amount. But subsequently I would turn on mobile data for about 1 minute to check a map and then straight off and I would get two sms's that night telling me I incurred another $100 total - ridiculous!!
Can I dispute this?
