It's a major fail from Optus

I am not a big fan of Optus.

First they have claimed to have mobile telephone coverage in areas in which they don't.

Second, the gave a high-paying job to disgraced former New South Wales state premier Gladys Berejiklian.

Third, they cynically almost doubled the price of an Optus Sports subscription - I opted out.

Now they cannot keep their customers' personal details safe.

Today, Optus still doesn’t know whether hackers who stole the personal data of up to 9.8 million of its users on Wednesday were private criminals or state-sponsored lunatics.

And the telco is also still unsure how many customers have had their personal information - including email addresses, phone numbers and identifying documents - exposed to the hackers.

But in a stage managed media briefing on Friday, Optus CEO Kelly Bayer Rosmarin said she was “angry” about the hack, which has been described as the largest data breach in recent Australian history.

This is the woman who earlier this year, announcing the Berejilkian "coup", said: “Optus has set its vision to become Australia’s most loved everyday brand with lasting customer relationships by redefining what customers should expect from their communication provider through our relentless pursuit of best-in-class service, greater innovation, better value and connectivity for all Australians.”  

But she's angry. Well done Kelly. Maybe get your people to do a better job next time. If you have any customers left.
