Customer service works in two directions, and AI agents are showing up on both sides. Businesses use them to answer common questions and sort tickets, while customers are starting to use their own agents to deal with companies: chasing refunds, asking for credits and getting through support chats.
This guide gathers real examples of both. Some cases show agents drafting replies, triaging requests and looking up answers for a support team. Others show people handing an agent the frustrating job of contacting a company on their behalf. Every case links to its public source.
Clear instructions matter more than anything here. Agents do best when they know exactly what outcome is wanted, what they are allowed to agree to, and when to stop and check with a person. That keeps conversations polite and productive and avoids promises nobody intended to make.
Whether you run a support desk or simply hate waiting on hold, browse the cases below for an approach that fits. Each page has a reusable prompt you can adapt and tips for staying in control. The most interesting cases are listed first.
What is in this guide: 60 sourced cases, added between 2026-10-15 and 2026-10-15. The tools that come up most often are Custom agent (13), Meta Muse (9), Claude (9), and the cases mostly sit under Finance (11), Shopping (11), Travel & Booking (9). They were reported on X (25), Reddit (15), Blog (9). If you only have a few minutes, start with the top three: “Work helpdesk tickets”; “Support call summaries”; “Win a flight refund dispute”.
Each case page gives a short summary in our own words, a note on why it matters, a reusable prompt broken into steps you can follow, and a link to the original first-hand account. Nothing here is a paid placement, and we only list cases with a working public source.
