Strong evidence follows FTC guidelines: clear, verifiable, timestamped docs. A 2025 Amazon case study showed a buyer winning a $500 refund with just an order receipt and defect photos--seller couldn't refute it. Screenshots boost success by 50%, per consumer reports.
Screenshots and Email Confirmations as Evidence
Digital proofs shine for order issues. Capture:
