Nationwide Building Society has issued an update after a customer reported see suspicious activity on their account statement.
The person contacted the group over social media claiming they had cancelled their card after noticing a payment for something they had "never done", for a Ring doorbell subcription.
They went on to say that some £130 had been taken out of their account and that they would contact their local branch about the matter.
Nationwide said in response: "If you believe there is a fraudulent transaction on your account, you will need to report this to us.
"Please call us on 03457 30 20 11, the lines are open today until 8pm and a member of our dedicated team will be able to assist you further."
Nationwide was asked what the general advice is if you notice a suspicious payment on your account that you don't recognise. A spokesperon said: "If someone notices a suspicious payment, they should call their bank or building society immediately.
"Whether it is an email asking for personal information or for you to click a link, report it as we have a team available 24/7 dedicated to fraud for this very reason."
The group also shared some tips for keeping your bank accounts secure: "When it comes to keeping your bank accounts safe, the best advice is to shred old financial paperwork such as bills and banks statements while changing your passwords regularly and not writing them down. Lastly, keep an eye on your bank statements to spot and report any fraud sooner rather than later."
