Poshmark is an advertising business for other businesses to advertise their goods or products. My business listed on there is Muscle Car Garage. I retail die-cast toys model cars, trucks, aircraft and plastic model kits. I sold an item that was purchased by the customer. The Company kept asking for my phone number I submitted it to Poshmark and they claimed they sent me a code. I never received it therefore I lost a sale because of their incompetance to answer my emails and phone calls to which they don't answer! This Company should be shut down!
