Commonwealth Bank of Australia (CBA) has once again been hit by IT problems, leaving customers unable to use ATMs, point-of-sale terminals and call centres.
Many customers were unable to withdraw cash and make payments at cash machines and eftpos terminals for approximately five hours before systems were restored by around 7pm local time. However, phone banking was still not working at the time of writing.
The bank used its NetBank Twitter account to try and placate angry customers but staff appeared to be fighting a losing battle, with one Tweeter, sandral_23, telling the world: "i officially hate @NetBank. Absolutely hopeless. I think it is time I change banks!"
Only last month, CBA, which is in the middle of a $1.1 billion core banking system upgrade, suffered a technical error that locked customers out of its NetBank site.
In March, 'routine' overnight database maintenance' left customers unable to transfer money or pay bills via the bank's online and phone banking services, and caused some cash machines to spit out large amounts of cash to customers with no funds.
CBA is not the only Australian bank to be hit by IT issues though; WestPac and NAB have both suffered repeated ATM, POS and online problems in the last few months.
