Mercari complaint: TOO MANY FRAUDULENT SELLER’S..

I am new to this app made the mistake of trusting that Mecardi would refund me for my purchases if they were not authentic. I have watched so many people get scammed on PANDORA charm’s daily. I trusted that the rating were legit but the seller is selling fake fake fake Pandora charms bracelet’s and has been doing it for a long time. It’s sad to watch people get burned and not be able to stop it. I now have 3 fake Pandora braceletsand charms in the first week.
I am hoping for some oversight and take your complains more seriously. The first seller I reported as fraudulent included pics with my complaint. The seller had no rating but assured me they were real. What I received was a bad imitation including the pouch it even came in. I reported for days hoping to stop the next person from getting scammed. I did not rate the buyer yet this seller has 3 ratings now which means 3 more people didn’t get what they thought they were. The next seller had the highest rating and guess what ?? Fake Fake Fake !!! You would think you could trust someone with 300 gold stars. I took pictures of the real charms next to it and although they were good they were not authentic Pandora. I looked and this seller has dozens and dozens of fraudulent items posted and people are buying stuff today. Can I at least get my money returned to me?? Please investigate these sellers stop allowing them to sell on your site.
