I bought a package of Hyperikon T8 tubes. When they arrived 6 were new and 9 were junk with the ends cut off. The seller listed them as “new”, had pictures of only the good tubes, and the price was 32 and 80 something shipping. He did refund the whole purchase price but with shipping it was a rip off. I never would have paid that amount of shipping for 6 tubes.
Then when I left negative feed back with screenshots of the listing, he started calling me names in messages. I reported him but as you say eBay really doesn’t care about bad sellers.
I had bought a pristine, autographed Fergie Jenkins baseball off of Feebay and the seller mailed me one that was toned with a faded signature. Filed a claim & the seller couldn’t understand why I wanted a refund in spite of the fact that what was advertised, didn’t match what was delivered.
