Commonwealth Bank customers have found their account balances lower than they should be after the bank charged some transactions twice.
The duplicates involve transactions from recent days and have resulted in some people having their bank accounts overdrawn.
The Commonwealth Bank said it was working to reverse these transactions “as a matter of urgency” and that any fees charged would be refunded.
The bank issued an “important message” on Saturday morning to customers, saying “we are aware some customers are seeing duplicate transactions from payments”.
It told customers it was “sorry for the inconvenience. Thanks for being patient with us”.
However, for some the lack of funds was a matter of urgency. Some took to X, formerly Twitter, and described being unable to pay for essentials including medication, fuel and food.
One person on social media said they risked missing a flight because their account was overdrawn, leaving them without enough funds to get transportation to the airport.
Another described the embarrassment of being at the register and finding themselves unable to pay for their food.
For some, their weekend plans have had to change – as one person put it, “this has fucked up my Saturday. Thanks Commbank.”
While the bank said it was treating the issue urgently, customers were demanding to know when their money would be returned.
One customer said they had “hundreds” of duplicate transactions on social media.
Customers are also asking why it has taken the bank so long to notify them of these duplicate transactions.
Some on social media vowed to move banks after their funds are returned.
