Ok I sell very high end salon products on eBay. All my stuff is authentic as I get it straight from the manufacturer. I've even walked the production floor so I know this is as authentic as it gets. I have a customer who bought some conditioner in July (yes july) and is now complaining that I sold her fake conditioner. She claims "that all the other alterna 10 conditioners I have purchased, including those at my colorist, have been very thick. This one is thin, thinner than the shampoo, has a different scent and texture." Now I do know that they reformulated this conditioner to be thinner as there were complaints that it wasn't coming out of the bottle evenly enough. What to do. Obviously since she has left me feedback saying "authenic product fast delivery" when she first got it and its past a 45 day paypal she can't do anything about it but it makes me so mad for her to think its fake. Do I need to send a snap of the bottle coming off the line or will she think I have my own factory?
