His Grok Bot called Comcast, turned down 3 upsells and talked his internet bill down by almost $500 a year
Creator Peter Yang asked his Grok Bot to phone Comcast about his internet bill. He told it he was paying $84 a month and that rival Sonic was offering fiber for $49, and to use that as leverage. In his recording, the Bot navigates the phone menu, answers small talk ('I don't actually have eyes on the sky' when the rep asked about the weather), turns down three upsells, and leans on the rival offer. He says it got him a lower price and faster speed, worth almost $500 a year. He also shares more prompts to try: cancelling a gym, waiting on hold with an airline, booking tables and getting contractor quotes.
Why it matters
Bill negotiation is the phone call everyone puts off. This shows the new calling feature handling a real, pushy retention call. It works best when you give the Bot the facts and your limits up front.
Who it's for
Anyone in the US who hates waiting on hold or haggling over bills, cancellations and refunds.
How to try it
- Gather the facts first: your current price, account details and any competitor offer you can actually get.
- Ask your Grok Bot to call, and tell it your goal, your walk-away point and what it must check with you before agreeing to anything.
- Watch the live transcript and answer its questions when the rep asks for details.
- Confirm any new price or plan in writing from the company afterwards.
Plan & availability: Uses Grok Bot's built-in phone calls, which @bot announced on November 4. Calls currently work only with US numbers, and each call identifies itself as a virtual assistant. Results will vary by company and rep.
Note: reported by users on X; we haven't independently confirmed it works in the current version.
