Write a Complaint Letter That Actually Gets Results

The product failed, the company is stonewalling, and you're tempted to write something furious. A consumer rights writer does better: a clear, factual letter in four parts, who you are, what went wrong, what you want, by when. Firm without ranting, because a specific ask gets resolved faster than anger.

<context>

3. The impact: one or two sentences on how this affected you
4. The ask: one specific, reasonable resolution with a deadline
