How to report a fraudulent transaction on your Zempler card

If you’re concerned about your card, temporarily block it in the Zempler Bank app or Online Banking.

To do this, go to Cards > Block card > Temporary Block.

Seen a transaction you don't recognise? Here's what you need to do:

If you’ve been a victim of fraud, you’ll likely realise when there’s a card transaction on your account that you didn’t make.

Review the transaction

  • Check your statements to make sure you have all the details of the unusual activity and transactions.
  • If you have additional cards connected to your account, check with the other cardholders whether they have made the payment or have possibly set up a regular payment.
  • Check how many payments you’ve made to this merchant and whether it’s a regular transaction set up previously. For example, it may be part of a free trial that has not been cancelled.
  • If you think you’ve used the merchant previously, you should contact the merchant as well as Zempler.
  • If the merchant is familiar but the amount isn’t, check whether the merchant is based overseas. If they are, check the exchange rates as foreign currency transactions may be different in GBP, which may be why it isn’t familiar.
  • Check the business name. Some may show as a different name on your statement to the business you have made a payment to.

If you still don’t recognise the transaction

  1. Block your card

    Block your card in the Zempler Bank app or Online Banking so that no further transactions can be made.

  2. Contact us

    Contact us on 0330 024 0924 (from abroad call +44 207 153 8940), or report on Online Banking:

    • If you suspect your account has been fully compromised by a fraudster, we can block the whole account. We will then need to verify your identity and address to reset it.
    • Our team may request follow up details. Please provide these to us as soon as possible.
  3. Contact Action Fraud

    Contact Action Fraud (the UK's national reporting centre for fraud and cyber crime) via their website or on 0300 123 2040.

  4. We'll provide an update

    We’ll provide an update on your case within five working days provided we have all the information we need from you.

Report a card as lost or stolen

If your card is lost or stolen, you can report it as lost or stolen in- app, Online Banking or by calling us.

FAQs
