What you should do

  • Do not share personal or bank details with an unexpected caller. Banks, HMRC and the police never ask for PINs, passwords or one-time codes.

  • Block the number if the calls are unwanted (see below).
  • Report it above, and report scams to Action Fraud. Forward scam texts to 7726 for free.
