# What should I do if I suspect fraud on my Halocard?

If you believe a transaction may be fraudulent, act immediately. Locking your card and contacting support helps prevent further charges and protects your account.

###### Step 1: Secure your card

As soon as you suspect fraud:

1. Lock the affected Halocard immediately to stop further transactions
2. Contact Halocard support so we can assist

###### Step 2: Review the transaction

Before assuming fraud, review the transaction details:

* Review the merchant name, as some businesses bill under a different name (i.e. a parent company)
* Check whether the amount or date matches a recent purchase, subscription, or trial
* Look for duplicate charges, which may be pending or reversed
* Confirm whether anyone else with access to the card could have made the purchase

A charge may be fraudulent if:

* You do not recognise the merchant at all
* The amount is clearly wrong
* You are confident the purchase was not made by you or anyone authorised

###### Step 3: Contact support

We’ll review the transaction, help secure your account, and guide you on next steps. Depending on the situation, this may include raising a dispute or issuing a replacement card.

###### Recognise the transaction but something looks wrong?

The charge may be a billing issue rather than fraud, in which case please refer to: [How can I dispute a transaction and request a chargeback?](https://support.halocard.co/en/article/how-can-i-dispute-a-transaction-and-request-a-chargeback-dqmc7m/)
