Please don't waste anymore precious time trying to contact CS , as they will not take ' evidence' from photos that an item is fake, or that the caller is genuine , as you could be a disgruntled buyer, or even a competitor.
eBay work on cases, and they work well.
If buyers are buying these items only to find they are fake, they can receive a full refund under eBay's 30 day MBG policy, which is written on every listing.
If too many of these return cases are opened, it raises red flags to eBay, who can then investigate further and can remove the item(s), or seller permanently from their site.
