The finance committee and I have just gotten back from Ozz and today the normal monthly phone billed arrived. I was some what surprized to see she had been charged $42 for extra calls outside her roaming package that always showed she had minutes available outgoing. I seems from what I can see in the Spark app that it can take up to 4 days for your minutes totals to update. Are you kidding me in 2019?? I was roaming on Skinny and their app showed the minute count as soon as the call finished.
You need to sort this out.
In saying all this the roaming worked 100% from the time she landed until we departed. She was roaming on Optus.
