FRUSTRATED customers have been left unable to use TSB’s mobile banking app this morning.

The bank says it has resolved the problems which affected a “small number” of its customers on the first Monday of the month.

Many customers took to social media to say they were having trouble carrying out transactions.

Last week, TSB announced plans to shut another two branches in Dorset and one in the New Forest. Its Poole branch was already due to close this month.

TSB told customers: “We’re aware a small number of customers are experiencing difficulty logging into the mobile banking app.

“We’re looking into this and we apologise for the inconvenience to anyone impacted. We recommend customers try turning WiFI and/or mobile data on and off to see if that resolves the issue and try logging in again. Alternatively, customers experiencing difficulties can use internet banking, on our website, or telephone banking.”

Responding to complaints via Twitter later, the bank later added: “We’re aware that a small number of customers have reported problems logging in to our online services this morning.

“These have now been resolved so please try logging in again. We apologies for the inconvenience.”

Many users had taken to the social media platform to complain, with some threatening to change banks.

One wrote: “TSB closing branches all over UK including my local branch leaving me six miles from my nearest branch. Reason? We are all using online banking so much more. Tried using mobile app and it's down.”
