.If the listing misdescribed the item (not a minor thing like calling a red sweater scarlet when it is actually cherry but counterfeit ) then you can Report the listing, or any similar listing or relisting by the seller.
All you will get from this is a polite note thanking you for your Report.
BUT
That is a cya by eBay's lawyers. They want up to police the site, but won't encourage vigilantes.
Nonetheless, these Reports are considered and from time to time we see sellers suddenly go NARU (Not a Registered User). That means they have been kicked off the site.
If the seller did not ship* after you paid, you got your money back, but just as important the seller now has a Defect on his account. Again these can build up and lead to a NARU seller.
I doubt this will arise in future, most problems are with the first few transactions with newbies, whether they are buyers or sellers, but if you ask here for advice, the best method of solving a problem will be discussed by experienced nosyparkers members.
*More likely than the postal system losing the item. Delays are fairly common, but actual loss is rare. I speak from about 30 years in mail order.
