How do you say "I got the wrong item" in Japanese?

Quick use

Use ちがうものがきました (chigau mono ga kimashita) at a restaurant when the wrong item came.

Chunk or pattern

• This is best learned as a practical chunk.
• Learn the whole line first instead of rebuilding it word by word.
• It gives staff the problem clearly without sounding too sharp.

Core words

• ちがう: different / wrong.
• もの: thing / item.
• きました: came / arrived.

Practical note

This is softer and clearer than only saying これじゃないです. If possible, point to your order or the menu item you expected.
