A $9 hotel invoice mistake fixed by Muse

His hotel invoice had a $9 mistake on it. On its own that would sit at the bottom of his to-do list, but he travels a lot and says these small errors add up. Meta Muse got the invoice fixed. He says the hard part was finding where to send the request, because hotels leave the email address off, and Muse found it. Small billing fixes like this are a good job for an agent: the amount is low, the evidence is the invoice itself, and nothing needs your card or a phone call. If you expense travel, it also saves a messy back-and-forth with your company later.

Copy this prompt

Here's my invoice from [HOTEL] for my stay on [DATES]. The problem: [WRONG CHARGE, AMOUNT]. Find the right contact for billing at this hotel (front desk or billing email, not a general reservations line). Draft a short, polite request to remove the charge and send a corrected invoice, with my confirmation number. Show me the draft before you send it, and tell me when they reply.

Our own prompt, written from what the source describes. We haven't run it ourselves. Text in [BRACKETS] is what you replace.

Watch out for

  • Show the agent the invoice and your booking confirmation so it quotes the right numbers.
  • Ask for a corrected invoice, not just a refund, if you need it for expenses.
  • Approve the email before it goes out. It goes out under your name.
