Beware to anyone that uses Authenticatemybag.com!!!! I sold a Chanel tote that is a 17 series on eBay. It was purchased last October. The Chanel store still had one in stock. Well the buyer is claiming its a fake!!! They supposedly used this service to authenticate and it said that because it was purchased October 2015 and the serial number starts with 17 it's a fake!!! Now I'm being forced to offer a refund when I don't have the money anymore!!!! Beware!!! Is there ANYTHING I can do here???
