Hi ... I also put notes in all my items I post, but if they don't receive the package...they don't see it OR if they do, they just ignore it.

I also send an email to each customer after their purchase to make sure they know my terms and conditions and subtly ask if they have read the item description.

If they are not happy, I'm happy to refund their money, BEFORE I post the items.

Most are fine and say thankyou. This has worked well for me, but I occassionally get a buyer who missed reading the items are DIY or the sizing etc

They either go ahead or ask me to cancel. I put that through ebay as " customer changed mind "

So, for me I don't get as many item not as described.
