Commonwealth Bank says it is aware of 'duplicate transactions' as ...
Commonwealth Bank users are reporting an error which has seen duplicate transactions being taken out their bank accounts, resulting in overdrawn accounts for some customers.
The bank said it was it aware "some customers are seeing duplicate transactions from payments" in a statement to the ABC.
"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."
Melbourne man Tom Kelly first noticed the error when he tried to buy a coffee at work on Saturday morning and found his account was overdrawn by more than $100.
He had no communication from the bank and said he initially "couldn't work out what was going on".
Hours later, he said he had been put on hold for 40 minutes and couldn't access the bank's online chatbot Ceba.
As of 12pm AEDT, the digital assistant still appears down.

"I'm worried I won't be able to get an Uber home from work," Mr Kelly said, noting public transport added a significant time to his commute home.
"[Even then] I've got to make sure I have enough to tap on."
Mr Kelly said he had filed a complaint with the Australian Financial Complaints Authority.
"It's unbelievable," he said.
"We're not all rich and well-off.
"There's some people out there where those transactions are the last dollar for the week."

User Chris told ABC Radio Melbourne his account was also overdrawn by "the hundreds".
He said he has had "no communication or acknowledgement" from the bank's end.
"Acknowledgement would have been great from the start, but then what are the next steps would have been great," he said.
Chris said the error had put his weekend in disarray, including a first birthday party he was planning.
"We're just trying to figure out if we can use our card," he said.
"Ok yeah we can move money from our savings for spending but is that going to be overcharged?
"There's a lot of expenses involved, in terms of catering, so you know if you're spending $500 is it $1,000?
"You don't have that confidence in going to the shops."
One customer on social media said they had been at the pharmacy to buy medication when they noted five duplicate transactions.
It comes as Westpac and subsidiaries including St George, Bank of Melbourne and BankSA were hit by a string of outages last week that saw customers experience difficulties accessing internet banking for three days.
