What they did

After a rent payment failed through a new bank account, a renter was hit with a $50 late fee and a $25 ACH fee. He gave OpenAI's computer use agent his emails, payment confirmation, return notice, statement and lease. It asked for a manager's review, wrote to the corporate office and filed BBB and California consumer complaints.

Result (as claimed)

The next day both fees were reversed, a $75 credit after about a dozen emails he did not have to write.

Tools they used

Cost: Pricing depends on the tools you pick; check each official pricing page.

Set it up

  1. Define the job

    Say exactly what you want done and what the agent may and may not do on your behalf.

  2. Share only what is needed

    Give ChatGPT the minimum files or access required. Avoid sharing passwords in chat when a safer login flow exists.

  3. Review the plan

    Ask the agent to show its plan or draft before it acts, and approve each step that has real consequences.

  4. Check the result

    Confirm the outcome yourself (order placed, request sent, document understood) and keep a record.

Copy the full setup prompt

Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Please:
1. Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like).
2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure.
3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data.
4. Finish with a checklist to run it again next time.
