I sold multiple pieces of luggage on Mercari and was charged outrageous shipping fees — $95, $95, and $140 — even though the items were light and properly shipped. Mercari falsely reported the weights and then refused to release my earnings, even though the buyers paid for shipping and the items were successfully delivered.When I contacted customer service, I was met with dismissiveness. I informed them I would report their fraudulent actions to the Better Business Bureau, and they told me to “go ahead” and marked my case as “resolved” without helping me at all. That’s not just bad customer service — it’s unethical and feels like a scam.I depend on the money I earn from selling for groceries and bills. Mercari took that away with no accountability. This is how they operate — pushing all the costs onto sellers and then making excuses when something goes wrong.Let me be honest:If anyone has a good experience with Mercari, it’s likely because they never had to deal with their administration or customer service. The moment a real issue comes up, Mercari only cares about getting the maximum money from both buyers and sellers. They don’t care about doing right by the people who keep their platform running.There’s a reason Mercari has a 1.3-star rating and over 20,000 negative reviews. These aren’t one-off issues — it’s a pattern of bad business practices and fraudulent behavior.I’ve submitted this to the Better Business Bureau and urge others to do the same.
