Dear [Name],
Thank you for your prompt response. I appreciate your willingness to look into the matter and provide me with an update. I understand that you will be following up with your Food and Beverage manager to clarify the charges for breakfast on the day in question. I look forward to hearing back from you by Tuesday.
I also appreciate the credit of $120 for breakfast that has been applied to my account. I will await the full details on the check before deciding whether additional compensation is necessary.
Thank you again for your attention to this matter.
Best regards, [Your Name]
