VOA一分鐘英語 怎樣用英語禮貌地投訴？

在消費者對服務感到不滿意時，通常可以向商家投訴。用英語投訴時，用哪些句式和詞語聽起來才更禮貌？哪些單詞可以被用來加強語氣，突出對某件事情感到 “非常” 不滿？
 
Sometimes we need to complain. But, how can we do this politely and in a British way?
First, we can begin 'would like to' to say what we want.
Hi, I would like to speak to the manager. Yes, I'd like to complain.
We can say 'I am unhappy about' plus a noun phrase.
Yes, I am unhappy about my late delivery.
We can also add 'very' or 'really' to make this stronger.
Yeah, I'm really unhappy about this.
We can also say 'it's unacceptable that' plus a clause.
Yeah, it's unacceptable that my delivery is late.
Remember, don't lose your temper. This means don't 'become too angry'. It's rude to lose your temper. This is good advice – we can say this to people who are angry with us.
Alright! Don't lose your temper.
 
用法總結
 
用 “would like to” 提出 “想要” 投訴。
I would like to speak to the manager.
I'd like to complain.
 
用 “I am unhappy about + 名詞短語” 的結構表示 “我對…不滿意”。使用副詞 “very” 或 “really” 來加強語氣，表示 “非常” 不滿。
I'm unhappy about the food.
I'm really unhappy about the food.
I'm very unhappy about the quality of the product.
 
用 “It's unacceptable that + 從句” 的結構表示 “… 是不能接受的”。
It's unacceptable that you forgot my order.
It's unnacceptable that you expect me to pay for the damaged goods.
 
注意，不要 “lose your temper（發(fā)脾氣，發(fā)火）”。
stop shouting – don't lose your temper.
