Lost card or suspicious transaction
Report a lost or stolen card promptly to Credit Union SA on 13 8777 during business hours. Outside business hours its Fraud Bureau Service is available on 1300 705 750. If a transaction looks wrong, ask to raise a transaction dispute.
For a misplaced card, use the card controls in the issuer’s app or Internet Banking to lock it temporarily.
Reduce your limit or close the account
In the issuer’s Internet Banking, choose Cards → Card Management. In the Mobile Banking App, open Card Management and select the credit card. Follow the prompts to reduce the limit or cancel the card. For account closure, confirm the outstanding balance and closure arrangements with the issuer on 13 8777. A temporary lock keeps the account open.
Financial hardship
If a repayment is becoming difficult, contact Credit Union SA on 13 8777 or send a Secure Mail message through its Internet Banking and ask for hardship assistance. The issuer assesses requests individually.
