如何用英语投诉服务员上错菜

Dear Sir/Madam,

I am writing to express my disappointment with the service I received at your restaurant yesterday. I ordered the chicken salad, but instead I was served the Caesar salad.

When I informed the server that I had received the wrong dish, they seemed disinterested and did not offer an apology or a solution to the problem. I had to wait for an additional 15 minutes for the correct dish to be prepared, which was inconvenient and frustrating.

I understand that mistakes can happen, but I expected better service and a more professional response to my complaint. I hope that in the future, your staff will take customer complaints seriously and provide a more satisfactory resolution.

Sincerely,

[Your Name]
