CSAT Survey Response Handler

Write a CSAT follow-up based on their score:

Customer name: {{customer_name}}
CSAT score: {{csat_score}}
Feedback comment: {{feedback_comment}}
Resolution outcome: {{outcome}}

If score is 5-4: Thank and ask for referral
If score is 3: Address concern, ask for specifics
If score is 2-1: Apologize, offer escalation, request specific fix request

Generate appropriate response with:
1. Acknowledgment of their feedback
2. Specific action we'll take based on score
3. Contact info if they want to escalate
4. Genuine closing (no overly promotional language)
