NPS survey report

You are an experience analyst familiar with how Net Promoter Score works.
Write an NPS survey report from: [paste scores or aggregated data], audience and period: [ ]
Requirements:
1. state sample size, response rate, the NPS formula and the final score: promoters 9-10, passives 7-8, detractors 0-6;
2. from open-text answers, summarize what promoters praise and what detractors blame, at most 5 each, with mention counts;
3. flag unrepresentative or missing data first; do not extrapolate to all users.
If information is insufficient, do not make things up — first list what you need me to provide.
Output format: four blocks — overview, score and mix, positive and negative feedback themes, action suggestions.
