FAQ
Q: Should I CC a manager or executive on my first complaint email?
A: No. Start with the primary contact. CC'ing higher-ups immediately can seem aggressive and may slow resolution. Escalate only after an unsatisfactory or no response.
Q: How many details about the bad service are too many?
A: Stick to 1-2 concrete, factual examples (e.g., 'Agent refused to transfer me,' 'Promised callback never came'). Avoid emotional language and lengthy narratives.
