RBS Group has confirmed Twitter reports of an online banking and debit card outage.
Online banking and debit card transactions have been hit, RBS said in a statement on Thursday.
"Some of our customers are experiencing technical difficulties this afternoon with online banking and debit cards," said RBS. "We are working hard to resolve this and will provide an update as soon as possible."
Some Twitter users reported their dissatisfaction with the outage, which comes only a month after a serious batch-processing error by the bank.
"Time to leave NatWest, I think," said Twitter user Tony Heugh. "Any recommendations for banks? Debit card isn't working so the bar is really low."
Last month RBS customers were hit by a balance glitch that caused issues for a number of NatWest, Ulster Bank, and RBS customers.
