You can leave feedback for sellers within 30 days in "Orders Awaiting My Feedback".
Feedback will be displayed and activated when both the buyer and sellers have left feedback or at the end of 30 days of order completion.
After feedback is left (by you or the seller) you will have 30 days to reply to, revise and/or report any abusive feedback for any of your completed orders.
After this 30 day ‘active feedback’ period is over, you will not be able to revise or remove any feedback. To view your feedback abuse report, click here to see my report list.
