Hi,
Go to your FB profile.Click 'Leave Feedback' at bottom left corner.You may retrieve some old ones.
In future,if you want to leave FB after 2/3 months,please save that item in 'list' in myebay.
Hope you got your answer.
Thanx,
Truly,
Amitava
When you didnt bother to leave feedback after receiving item why bother now. I am sure your item received has developed issues and hence you want to take the case of poor seller.
