Hello there, I am an honest eBay seller and have been selling for several years now. All my products are sure to be authentic as they were purchased from the designers boutiques, department stores, and the US outlets. Recently, one of my customer told me that my business was named selling fakes here in the Purse Forum by a TPFer. (The same TPFer has also authenticated my products previously.) I am not sure how he/she comes up with the comment. This hurts my business and it is libel. Should I ask him/her directly for reasons and proofs? What should I do now? Any advices, comments, suggestions are fully appreciated. Thanks in advance!
