Customers of Commonwealth Bank Australia (CommBank) have been left frustrated after a series of major outages left them unable to access their bank accounts.
The problems started at 8am Australian time when customers found their credit card balances missing from their online banking accounts and smartphone apps.
The issues have escalated as the day has gone on with customers reportedly left without wages and unable to use their credit cards while merchants have found a number of transactions have not gone through.
Unsurprisingly, irate customers took to social media to vent their frustrations and chronicle their complaints, from being left red-faced at supermarket checkout counters to being unable to eat at McDonalds and stranded on public transport.
Meanwhile due to the problems affecting merchant services, one small business owner complained that he had "a fair few angry customers at my place of work".
As of 7.00pm Australian time, the problem had not been fully resolved although the bank did issue a statement to customers on its Facebook site.
"We're aware some customers may be experiencing intermittent issues with NetBank, CommBank app and CommBiz," it read.
"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. We'll keep you updated as new information comes to light."
As of yet no cause has been given for the outage and no estimate of when the problem will be fixed has been given.
CommBank customers will be hoping that the issue is resolved sooner than the last major outage suffered by the bank, back in September 2015 when they were unable to access all of their banking services for 18 hours.
