I knew it was too good to be true a brand new Fendi B patent trim bag for £288?! It looked so real even the staff in Fendi Sloane Street had to really examin my bag and the one they had in store before they prounounced it fake! Anyway I got onto the seller and she agreed to give me a total refund but now I don't know if I should leave her negative feedback! She's agreed to the full refund and apologised profusely so it seems mean to leave negative but if I don't leave other people a warning she might keep selling fake bags that are so good unless you live near enough to the designer to go in and get them authenticated you would never know they were fake! I don't want to encourage the sale of more fakes on eBay but do I jeopardise my 100% positive feedback if she retaliates and is it out of order as she is being reasonable?? Help please!
