No need to email or contact eBay
eBay emails are bot automated and nothing to do with item not as described dispute
Very good advice to be ware (sic)
You need to follow the correct process or you won't get anywhere
And eBay have no idea if you use the site or not
Was this seller registered in China with horrid feedback?
