Customers of collapsed holiday firm Thomas Cook have been targeted by fraudsters posing as employees.
Trading Standards said it has had "multiple reports" of people in Norfolk being called with a fraudulent offer to refund their holiday payment.
The caller poses as a Thomas Cook employee and asks for bank details to facilitate a refund.
"The caller advises that they are calling to refund their holiday payment, and that to do so they require the recipient's bank card details, including the 3-digit card security code," said Trading Standards.
They added this is a scam.
"No Thomas Cook employee will be calling those affected by the company collapse," said Trading Standards. "Refunds will be issued by the CAA, and they will not start being processed until 30th September."
Anyone being targeted by the scam can call Norfolk County Council Trading Standards on 03454 040506.
