When to Complain in Writing vs by Phone

Each has different strengths depending on the situation.

1. Writing creates a paper trail — better for anything that might need escalation or legal follow-up.
2. Phone is faster for time-sensitive issues where you need an immediate resolution.
3. For complex issues, a written complaint followed by a phone call for urgency often works best.
4. Always follow up a phone resolution with a written summary email confirming what was agreed.
