Write a complaint letterto express your bad experience when you purchased a good or a survice

Dear banana restaurant I am not satisfied with the survival of Staff, so I have to write this letter to complain about this problem. On 20th December, that day is my mother’s birthday, and I celebrated a party for her at this place. However, I was deeply dissatisfied because the low-quality service from the staff’s behavior was horrible. When I came restaurant, the service staff seemed to be tired or something that they did not greet us, not only showing discomfort faced but also leaving me speechless and angry without apologizing for the delayed service. I had to wait more than 1 hour for ordering some dishes. I was furious, and I then went to the receptionist to require the compensation. Unbelievably, they ignored me. Immediately, we left out of there. I hope the manager will consider and change the staff. I think that you had better give this issue your full attention and quickly solve it for me as soon as possible Yours faithfully. Đào Quang Nhân
