Your post has been moderated so I can't see any links to what you bought, but you asked if listings are checked or verified and is it fair you can't leave neg feedback.
No, listings are not checked and verified. There are some items you can buy on ebay where it will be authenticated (I think things such as some brand name sneakers or bags) but my understanding of that system is the seller sends them to an independent verification centre and from there, if all is well, they are sent on to the buyer.
I haven't bought those types of things but I imagine if they are going to be authenticated, it would say so in the ad. That would be a big selling factor.
Be aware that a lot of items on ebay (especially think Chinese items) are blatant fakes, so if you're spending a lot of money on something (or alternatively, see a big brand name at an unbelievably cheap price), probably best to steer clear. Some things are better bought at retail stores than on ebay.
As to what is fair-it isn't fair if the seller sent you anything other than what was in the ad. I have no way to judge that, I can't see the item or the ad. But if you buy anything that is very much not as described, you do need to take action within the time frame. You can open an ebay claim, but only within 30 days of ETA, I think it is.
You get 180 days if you paid via paypal so if that's the case, try with them.
Don't worry too much about feedback.
It sounds as if you messaged the seller a few times & had no response. Never put up with that rubbish. Always look after your own interests if there is a problem, keep an eye on the dates and if the problem is not resolved quickly, just open an ebay claim. You don't need the seller's permission to do it.
But paypal is your best bet for now.
