IN SCENES reminiscent of hacking drama Mr Robot, Commonwealth Bank’s customers have had their credit histories seemingly wiped out today.

Credit card balances disappeared both from the major bank’s smartphone app and its online banking facility, NetBank, after 8am, instead showing only the funds customers had in savings.

The Commonwealth Bank’s digital problems also appeared to wipe the balances of home and personal loans, travel money card accounts, and affected bill payments using BPAY.

Some customers were also stranded at store checkouts thanks to the glitch, with one woman reporting that she was forced to leave a supermarket “red-faced and embarrassed” after her credit card was declined four times.

Other CommBank customers reported debit cards being declined in stores, bank transfers to credit cards disappearing, being unable to activate credit cards, and wages failing to appear in accounts.

Selected stores were also unable to accept credit and debit card transactions from any Commonwealth Bank customer.

In a statement issued two hours into the outage, the Commonwealth Bank acknowledged the issues and said it was working to restore accounts and services as soon as possible.

“We’re aware some customers may be experiencing intermittent issues with NetBank, CommBank app and CommBiz,” the Bank said in a statement.

“We know that some merchant terminals are also impacted. For our customers impacted by this issue we are sorry, please be assured we are working on this as a matter of priority.”

But the Bank failed to rectify the outage by promised deadlines at 10am and again at midday.

The outage is the Commonwealth Bank’s first since a major restructure by new chief executive Matt Comyn last month that saw the departure of David Whiteing, who had been in charge of producing “world-leading application of operations and technology” for the institution.

More than 6.2 million Australians actively use the Commonwealth Bank’s online services, according to its 2017 annual report.

But many customers, worried their accounts had simply disappeared, had to find out about the outage from social media before the bank issued a warning through its smartphone app and phone lines.

Stranded driver Bryan Bugaoan complained to the Bank on Facebook that he was “stuck on the side of the road with an NRMA mechanic waiting to be paid” after his card was declined, while others expressed concern they would be slugged for late fees for loans payments they could not make due to the outage.
