Is it possible to amend feedback for a seller when you have already left feedback for them ?

[christinegiraffe]

I left feedback for an item (positive feedback) only to find out a few days later that the item was faulty. I would like to amend or add to my original feedback for the seller. Can I do this ?

you can't change the feedback you have left but you can add a follow up

Follow up on given Feedback

have you opened a not as described case in the Resolution Centre?

Thank you for the advice. I cannot open a case as I posted the items back to the seller using his suggestions which did not involve tracking or ebay returns. My mistake. Just wanted others to know of my difficulties getting a refund from this seller.
