It's so long ago that I last did one but I think you do get a notification. You need to check Paypal or the payment source from time to time to confirm.
This is one of eBay's "less than helpful messages" I'm afraid. The number is in the system from when it was given to Royal Mail; you need do nothing.
I would guess that the refund is being processed. Many sellers are not set up to deal with messages. The refund goes back to the source so if you used a card through Paypal it goes back to the card and takes a bit longer.
Sellers have 6 days after receipt to issue the refund.
