In the following sentence, are any commas required? I've heard of the Oxford Comma but don't know whether this applies here. The sentence is badly worded - I am not able to correct the writing - however I would appreciate advice regarding any commas that should be inserted and where. Thank you.
The typescript and list of comments and queries (and the invoice) must catch the 6 o'clock post.
