I’ve recently listed a few items on poshmark to sell. All the items were unworn Still with tags attached. The one item was a funnel neck scuba with tags attached. %100 authentic. Well the buyer just opened a case claiming its not authentic. And posted a picture of a different scuba showing no tags. What do I do?? Am I going to be out the money and the scuba from this scammer?? I’m not familiar with poshmark. And I can’t even figure out how to contact them about this. Please any help!
