Is the seller still registered, if you have not paid then you are under no obligation to complete, if you have and have not received the goods then if by PayPal claim it back through them.
When you block a person, they can no longer invite you to a private message or post to your profile wall. Replies and comments they make will be collapsed/hidden by default. Finally, you'll never receive email notifications about content they create or likes they designate for your content.
Note: if you proceed, you will no longer be following .
