TSB's online banking platform left several customers unable to access their own accounts, yet able to view other people.
Claims the problem is now fixed, however several of the bank’s customers were still reporting issues with one claiming to have been credited with £13,000, which did not belong to him.
Many customers had already taken to Twitter to complain about not being able to log into their online banking accounts or being able to transfer funds and make payments.
