My buyer hasn't paid after a week. What should I do?

[babole_man]

A buyer committed to buy, but since that day, a week ago, has not responded to invoices, emails, etc. What is the procedure I need to follow.

Hi ..open an unpaid item dispute..

No payment after 4 days , close and ebay will credit the item final value fee. Buyer's account receives a strike.

Ad buyer's ID to blocked bidders list..
