Troubleshooting Payment Issues
Payment Declined

- Contact your bank — some banks block international or online transactions by default.
- Try a different payment method.
Invoice Amount Seems Wrong
- Review the line items for unexpected charges or missing discounts.
- Check for prorated charges from mid-cycle upgrades or add-ons.
- Contact billing support with the invoice number for clarification.
Cannot Find the Pay Button
- Ensure the invoice status is Unpaid — paid and cancelled invoices do not have a payment option.
