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:
- Lock the affected Halocard immediately to stop further transactions
- 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
If the charge appears to be a billing issue rather than fraud, see: How can I dispute a transaction and request a chargeback?
When a charge may be fraudulent
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
What happens next
Once you 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.
