Write Customer Support Email Templates

Write professional, empathetic customer support email templates for the following scenarios:

Company type: [e.g. SaaS / e-commerce / service business]
Brand tone: [e.g. warm and human / professional / casual]

Create templates for each situation:

1. Acknowledging a complaint (before resolution)
2. Apologising for a service outage or error
3. Handling a refund request (approved)
4. Handling a refund request (declined, with explanation)
5. Responding to a feature request
6. Closing a resolved ticket
7. Following up on an unresponsive customer
8. Responding to a negative review publicly

For each template:
- Subject line (where applicable)
- Full email body with [PLACEHOLDERS] for personalisation
- A note on tone or things to customise per situation

Rules: Always acknowledge the feeling before offering the fix. Never use "per my last email." Avoid passive voice. Be specific.
