Summary
Grok Bot can now phone US businesses, and Peter Yang puts it to a real test: negotiating his Comcast internet bill. The video plays highlights from the live call, in which the agent navigated Xfinity’s automated phone menu, reached a human representative, and pushed for a lower rate.
The setup is simple. Yang created a Grok Bot called phone caller, told it he wanted to negotiate his cable bill, and supplied his address, phone number, his current $84 monthly price, and the fact that competitor Sonic had launched fiber in his neighborhood at about half the cost. Grok asked clarifying questions, such as whether the bill covered internet only, before placing the call. He also had Grok build an app showing the full voice transcript and call highlights.
The negotiation ended with a plan around $45 a month, locked for a year, saving close to $500 annually. Along the way the agent turned down three upsells, including the XPro Wi-Fi add-on, made small talk, and tended to follow up quickly during pauses. The video shows where the technology works well and where its behavior can feel impatient or odd, and why phone-only tasks like cancellations and bookings are a strong use case.
