Grok Bot found $6,480 paid for a service never received

Leo had paid a vendor $240 a month for more than two years. He set up Grok Bot as a finance helper and had it read every invoice and related email. He says it worked out that the service had never actually been delivered, built a timeline and drafted the emails, which he sent himself. The vendor said a refund had been issued, but it never arrived and he was charged another $240. Grok Bot drafted a complaint, the vendor admitted it had not closed the account properly, and he says it confirmed a $6,480 refund. The pattern to copy is the paper trail: dates, invoices and the vendor's own promises in writing.
