Grok Bot spotted a $222.20 coffee typo and got $200 back
Omar asked Grok Bot to look through his credit card account for anything he might have missed. It found a $222.20 charge at a coffee shop from February that was almost certainly a typo for $22.20. He had paid by tap, so he hadn't noticed it. Grok Bot found the email address of that exact location and drafted a message with the details. The next day the owner wrote back, apologized and confirmed the mistake, and Omar picked up a $200 refund in person. Tap payments rarely show the amount at the counter, so a yearly statement check catches errors like this.
Poster's claim, not verified: He says the owner refunded $200. We have not verified this.
Copy this prompt
Review my credit card transactions from [START DATE] to today. Flag anything that looks like a mistake: amounts far above what I usually spend at that merchant, an extra zero, duplicate charges, or merchants I do not recognize. For each one, show the date, merchant, amount and why it looks wrong. For the ones I confirm, find the merchant's direct contact for that location and draft a short, polite email with the date, amount and what I think it should have been. Do not send anything until I approve.

Watch out for
- Contact the merchant first, then your card issuer if they do not answer. Card disputes have deadlines, often around 60 days from the statement.
- Check the receipt or your memory before accusing anyone. Some large charges are real.
- Do not give the agent the card number itself. It only needs the transaction list.
