Hi, I'm sorry if there is already a thread about this but can anyone recommend a reputable authentication service? I recently sold a 2005 Chanel GST on eBay and the buyer does not feel that it's authentic because she is only aware of the newer versions and does not trust me as the hardware is a bit different. So I'm currently out of the product and the money. I've already posted in the Authenticate This Chanel forum but I am under a time constraint and I understand it takes them a while to go through all of the requests. I have already emailed Carol Diva and My Poupette with requests and have not heard back from them. Thanks in advance!
