TSB has insisted its technical issues are now resolved and advised customers affected to turn the mobile banking app off and on again.

Hundreds of users feared being charged late payment fees as pre-arranged payments didn't go through meaning bills were not paid on time.

However, the bank insists the issues have now been resolved and advised users that any ongoing problems stem from users trying to log in through old or bookmarked links.

Bosses have told frustrated customers to close the app completely before attempting to log in again.

The first day of each month is the most popular time for people to pay their monthly bills and a failure of online banking to process the payments on time meant they could be facing an extra fee for missing the set deadline.

There was fears that even those with more than enough money in their account to cover the costs could incur the fine through no fault of their own.

But despite assurances that Direct Debits are working as normal, customers have been taking to social media to vent their anger at the problems caused by the banking failure.

In a statement TSB said: "We are sorry for the difficulty or distress any customers may have experienced and we are working round the clock to put things right.

"Our mobile app and internet banking are available, any customers having difficulty logging in, should try closing their mobile app fully and then restarting it, or closing the internet browser and trying again. Direct debits are working normally."
