Frustrated with Return and Upset eBay sides with new buyer

[bosstar99]

Had a new buyer with zero feedback con me and they got away with it. Buyer swapped out his old switch with my new switch and sent me his old switch saying it was defective. I reported the buyer to ebay. I took several pictures of side by side comparison of my new switches vs the returned used switch to show it was extremely worn and used and not the same switch he purchased 2 weeks prior. I also scribe my initials very small into everything I ship out. My initials were not on the returned switch. Guess my 18 years of being a honest loyal eBay seller means nothing. Extremely upset and frustrated eBay sided with a  new buyer with zero feedback. I immediately blocked him from ever buying from me again. Sellers beware of buyers swapping out their used merchandise and sending you their old used junk. eBay will side with the buyer. Lesson learned.
