The invoice number is missing [STRIKE]inv no.[/STRIKE] [STRIKE]on[/STRIKE] from a shipping bill. How [STRIKE]to[/STRIKE] can I explain this to the supplier by mail?
Note my corrections above. It is important to follow these rules of written English at all times:
- Start every sentence with a capital letter.
- End every sentence with one appropriate punctuation mark.
- Always capitalise the word "I" (first person singular).
Remember that we don't start questions with "How to".
