RBS has said that its customers, as well as those with NatWest, Coutts and Ulster Bank should have all payments in their bank accounts by Saturday at the latest.
The update comes after it was revealed that some 600,000 transactions put through its systems had not worked properly, meaning money was not put into people's accounts as expected.
“We have fixed the underlying issue, we apologise for the inconvenience caused and we are working flat out to get these payments updated for our customers no later than Saturday,' RBS said in a statement.
"To any customers concerned about the implications of this issue we advise them to come into a branch or get in touch with our call centres where our staff will be ready to help. We will ensure no customers are left out of pocket as a result of this issue.”
It also issued a similar message on Twitter.

However, despite this promise customers of the bank have vented their frustration, noting that they will still be left without the cash they are owed for several days.

The incident is just the latest IT woe to hit the banking group. Several problems have affected customers over the past few years, such as in December 2013 when its systems were unable to cope with a surge in Christmas and Black Friday sales.
Meanwhile, NationWide customers were hit by a banking problem this week, after being unable to access their accounts when an IT maintenance upgrade went wrong.
