Fight a mattress warranty claim by email
A user's agent emailed back and forth with the mattress company's agent, citing laws and pushing aggressively, to resolve a warranty claim.
Done with Claude Cowork
What they did
User emailed the mattress company about a two-year-old warranty issue and spotted ChatGPT-style replies after one or two exchanges. They then set their own agent to handle the ongoing email thread, giving it instructions to cite laws and respond as an aggressive pain-in-the-ass customer while the company's side stayed polite.
How it went
The agents continued exchanging emails with no resolution or outcome numbers stated in the post.
Worth knowing
Anything touching money, benefits or eligibility should be double-checked against the official provider before you act on it.
Try it yourself with Claude Cowork
I have a warranty claim with [company name] for my [product, purchase date, and the defect]. Draft a firm, polite email that cites the warranty terms and any consumer protection laws that apply in [my state or country], and states the remedy I want. Show me the draft before sending anything, and when replies come in, draft each response for my approval until the claim is resolved.
