Express Yourself Making a complaint
You can express your dissatisfaction when something you buy is of poor quality or the standard of service you receive is not good enough in various ways:
I'm afraid I'm not satisfied with this.
I'm sorry. This isn't acceptable/​good enough. We've been waiting half an hour.
I'd like to make a complaint. The radio I bought doesn't work.
Excuse me—this isn't what I asked for. I'm having/​I ordered the soup, not the salad.
I'd like to speak to the manager. I've got a complaint about something I bought.
