Westpac's online banking service has been on the blink for the last three days, with users unable to process payments and update balances.
On a Web page meant to keep customers abreast of the technical difficulties, the bank wrote: "We're continuing to address intermittent issues with transactions, balances and Get Cash in Mobile and Online banking.
"We're sorry for the inconvenience caused and we are working to fix this issue."
People can log in to online accounts at times but the balances shown are way out of whack.

There are intermittent issues with transaction status & balances in Online+Mobile Banking and we're working to fix them ASAP. Our apologies.
