投诉信
开头句:说明投诉问题
I feel something should be done about…
I am writing to inform you that I find…unsatisfactory…
结尾局:期待解决方案
I would be very grateful if you could look into the matter as soon as possible. And I am looking forward to an early reply.
I believe you will take my complaints seriously, I would ask you to give back my money, or I would file my complaint to the authorities concerned.
