HSBC customers have had their cards refused and access to online and phone banking cut after a technical glitch at the bank.
The bank did not return requests for comment, but the HSBC UK press office tweeted that they were "experiencing some problems." Just before 4.45pm, the account said that ATMs were back up and running, and the remaining card services and internet banking were working five minutes later.
"Card terminals and internet banking should now be back on. Sorry and thanks again for bearing with us," the press office tweeted.
Customers had reported on Twitter that they have been unable to withdraw money since mid-afternoon.
Several posted screenshots of their online banking portals, which showed a window simply reading "sorry" in the bank's signature red text.
Calls made by the Huffington Post UK to phone banking service were met with an automated message saying that the service was not available.
