Please help! I recently sold an authentic Chanel east/west on eBay. It was originally purchased from Nordstrom in Seattle. A buyer won the bag, paid $999 and received it in immaculate condition with the original box, dustbag, all tags and the original receipt. She left me good feedback and I did the same. Now, a couple of weeks later she sends in a Paypal dispute and request a chargeback on her card. She claims that it is fake! Now there is a -$999 in my Paypal account. What can I do? The bag is authentic but she claims it is fake! Any advice would be GREATLY appreciated!!!
