TSB customers have claimed the banking app is down as thousands of people are unable to access their accounts.
More than 1,700 users reported issues with their TSB app, according to DownDetector, after it was revealed the service suffered an outage.
Furious customers have now taken to social media to complain after they were frozen out of their accounts.
One person wrote on X: 'Come on @TSB! I need the app today, you close all the branches down and still cant allow us to use the app! What are you expecting people to do exactly??'
Another said: '#TSB app once again down, becoming a joke at this point!'

A third commented: '@TSB online banking app seems to be constantly down. Any danger of getting it sorted?'
Earlier this month, the banking group said it is closing 36 branches and cutting 250 jobs across the business.
The group told employees today it would cut roles in its fraud operations and central operations, as well as its branch network due to the closure of 36 physical locations.
The full list of locations shutting down has been published, with the first branch closing in September this year.
Trade union Unite said the decision by the UK high street lender was a 'grave mistake'.
'These workers perform essential work in the fraud departments and across the branch network,' Unite's regional officer Andy Case said.
Unite said it will be holding fresh negotiations with TSB about ways to further reduce job losses.
However, TSB have said they have been forced to make the cuts in a restructuring plan in order to remain competitive, as 96 per cent of all TSB transactions now take place outside of a branch.

'The decision to close a branch is never taken lightly, but our customers are now doing most of their banking digitally and we need to move to a better balance of digital and face-to-face services.
'We remain committed to a national branch network and through innovation and integration with video, telephone, digital, branch and other face-to-face services TSB customers have more ways to bank with us than ever before.'
Following these changes TSB will have 175 branches across the UK.
A spokesman from the bank said earlier this year: 'We have been clear about our focus on reducing costs, but as with any announcements about changing how we operate, we always consult with our colleagues first.'
