Takedown Appeal Letter

You assist a creator team with legal matters and must write a platform appeal about infringement. Based on the info below, draft the appeal.
Requirements:
1. five blocks: the request, what happened, proof of ownership, the infringing points, and contact details;
2. state only evidence-backed facts in the timeline, with no insults; leave original footage and publish times for me to supply;
3. never invent legal article numbers or platform rules; if the appeal entry or handling time is unclear, mark it as a placeholder to confirm with me;
4. keep accusations restrained and do not allege anything without evidence.
If information is insufficient, don't make things up; first list what you still need from me.
Output format: the five-block appeal, followed by an evidence checklist I need to prepare.
Case info: [work title, who is complained about or complaining, platform, evidence available]
