If you believe there's been an error with the amount charged to your account, get in touch with us straight away at support@etrnl.com.au with your order number and a description of the issue. We'll review it and resolve it as quickly as possible.
It's worth noting that some payment methods (particularly buy-now-pay-later like Afterpay and Zip) may show pending charges or split payment schedules that can look unexpected — check your payment plan details first before reaching out.
