Major Commonwealth Bank glitch sees customers charged double

CommBank customers have woken to find funds had been taken from their accounts for transactions they had already paid for.

Commonwealth Bank customers have reported waking up to find they have been charged twice for transactions made during the week, pushing some accounts into negative territory.

Many CommBank users have taken to social media after saying they have been unable to get through to customer service to raise complaints.

Some have reported having hundreds of dollars taken from their accounts for transactions they have previously paid for days ago.

“Once I get my money back I’m switching to a different bank. This is beyond just a simple apology,” one person wrote on X.

There have also been stories of Aussies not being able to pay for essentials like medications due to their accounts being in the negative.

Another CommBank customer posted a screenshot of their account balance, showing it had fallen to -$2815.05.

CommBank has said it is aware of the issue and was working to reverse the transactions “as a matter of urgency”.

CommBank customers are reporting being charged twice.

Several people have reported their accounts being overdrawn by the unexpected deductions.

“Why is my account needlessly overdrawn? You have charged me some of my previous transactions twice? What is going on?” one wrote.

A woman said the bank had “just taken all the payments I’ve made this week out my account again”.

Another said: “I woke up with the same, $800 transaction from 3 days ago and I’m pissed.”

In a post on X, the bank apologised and said it would refund customers.

“We are aware some customers are seeing duplicate transactions from payments,” a spokesperson for the bank said.

“We are working to reverse these transactions as a matter of urgency and any fees charged will be refunded.

“We’re sorry for the inconvenience. Thanks for being patient with us.”

The Ceba chat bot on the CommBank app also appears to be experiencing difficulties, with messages failing to send.

People have raged about the issue, fearing it could impact their buying of essential items like groceries and petrol.

“My account is overdrawn! I have bills to pay and Children I need to feed! How does this happen!,” one said.

Another said it was “shocking” but may have been out of the bank’s control.

“Lots of people are living paycheck to paycheck and having this happen could seriously affect their weekend as the refunds won’t happen for multiple days,” theys said.

In one of hundreds of comments on the bank’s Facebook post about the issue, a mother said she could not collect medication for her daughter “because I'm overdrawn and can’t pay”.

One man said he could not buy his wife’s arthritis medication because of five duplicate transactions showing on his account.

“Thanks for the beautiful Saturday Cmmonwealth Bank … There isn’t a word to describe the frustration with this.”

– More to come.
