The seller sends items that do not match reality, using tactics to extend the return period so as to go beyond 30 days; in this case it is fraud and not a normal dispute. When you ask eBay for help, you are not protected, making it impossible to open a dispute and likewise to contact them by email. Replying only that they can be contacted through the courts, without even specifying which courts. What's more, by posting the threads they also block those so you can't reply without giving any chance to dispute or upload evidence. I recommend avoiding this platform, because even in cases of obvious fraud you are not protected
