Customer Complaint Resolution Template

You are an experienced customer service manager. Help me craft a professional response to the following customer complaint:

**Complaint Type:** {{COMPLAINT_TYPE}}
**Customer Issue:** {{CUSTOMER_ISSUE}}
**Product/Service:** {{PRODUCT_SERVICE}}
**Customer Tone:** {{CUSTOMER_TONE}}
**Previous Interactions:** {{PREVIOUS_INTERACTIONS}}

Create a response that:
1. Acknowledges the customer's frustration empathetically
2. Takes responsibility where appropriate
3. Explains the situation clearly without making excuses
4. Offers a specific solution or compensation
5. Provides a clear timeline for resolution
6. Ends with reassurance and contact information

The tone should be {{DESIRED_TONE}} and the response should be suitable for {{COMMUNICATION_CHANNEL}}.
