Questions & Answers about Rúguǒ nǐ méi shōudào tuìkuǎn, jiù zài liánxì yíxià kèfú ba.

Why is 没 used here instead of 不?

没 is used to negate something that did not happen or has not happened, especially in the past or up to now.

So:

• 没收到退款 = didn’t receive the refund / haven’t received the refund

By contrast, 不 is usually used for:

• habits
• general facts
• future refusal/intention
• adjectives

So 不收到退款 would sound unnatural here.

What does 如果 do in this sentence, and is it always necessary?

如果 means if and introduces the condition:

• 如果你没收到退款 = if you haven’t received the refund

It is a very common way to mark an if-clause.

It is not always strictly necessary in conversation if the context is already clear, but using it makes the conditional relationship very explicit and natural, especially in standard written or careful spoken Mandarin.
