Important Fraud Update

Fraudsters are currently targeting businesses using impersonation tactics and can claim to be your customer or supplier.

You may receive an unexpected credit into your account, which will be followed up by a phone call, message or email. The caller or sender of the email, will claim to be your customer and advise the payment you have received, was made in error. They will request that you transfer the funds back to them but will provide a different IBAN number.

Don’t act on these payment requests as your customer may also be a victim of fraud.

Verify all payment requests on a known and trusted contact number. Do not use the contact details contained in an email or email attachment.
