Dear Austin Parker,
We have received the credit card statement for our corporate account. Before we settle the amount, though, we would like to ask that the records be corrected. The statement shows that the company booked three hotel rooms for a business trip in Paris last month. We only booked two. Attached is the hotel voucher as well as other pertinent materials which you may find useful. Should you have any questions, please feel free to contact us at 434-3434. We hope you can look into this right away and make the necessary changes as soon as possible.
Sincerely,
Isis
