My card was declined, how can I resolve this quickly?

Declines are commonly due to 3D Secure challenges or international usage rules.

1. Check available funds and complete any 3D Secure prompts.

2. Enable international/online usage with your bank app.

3. Try another card or method if the issue persists.

If your bank flagged the charge, ask them to allow Qoolline and retry.
