Put them on your blocked bidders list
Go back and scroll down to Stop Blocked bidders from contacting me
It will not work if you are in a transaction with them
https://www.ebay.ie/pages/help/sell/buyer-requirements.html
It says Bidder but really it should say blocked member list
The app is hopeless too few options available. Also remember when blocking further down the same page is a little box to tick to stop unwanted messages from them. Of course if you have been in a recent transaction with them they will still come through for a while before completely stopping.
