TSB customers in Andover should now be able to access their accounts after losing access for the last five days.
The banks upgrade caused chaos for customers stopping them accessing their accounts.
CEO Paul Pester Tweeted earlier today “Our mobile banking app and online banking are now up and running. Thank you for your patience and for bearing with us.”
The bank is apparently currently limiting how many customers can get connected for fear of the system being overwhelmed and crashing.
