Poshmark.com I advertised my products on their site and they would not give me customers address to ship the merchandise Redwood California

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!
