Santander customers can resume using their mobile and online banking as normal after a service failure.
Santander said its services were back to normal after a technical glitch that lasted much of Saturday, preventing customers from making payments.
The bank apologized for the inconvenience caused.
Customers said they couldn’t use the app or their online banking.
Consumer organization Which one? said some people said they couldn’t buy food at the supermarket, while one person tweeted that they had an “unpleasant and embarrassing” experience when their card was refused in the queue while she was trying to pay for gas.
In a statement released on Saturday evening, a spokesperson said: “All of our banking services are now operating normally.
“We are very sorry for the inconvenience you encountered today. If you need help, some of our branches will be open on Sundays from 10 a.m. to 12 p.m. We will publish a list of these tomorrow.
The bank had previously assured customers that “no one would have to pay” as a result of the problem.
Earlier today, the bank informed customers that they can access cash at other banks’ ATMs.
Gareth Shaw, Money Manager at Which ?, said the technical issues would have caused “stress for many Santander customers”.
He added, “These issues demonstrate why it is vital for banks to invest to ensure that their systems are up to the task of protecting their customers’ accounts and maintaining the services they rely on.
