Poshmark review: Customer service

I've been a seller on Poshmark for 4 years. Last week, I sold a pair of pants on Poshmark. They were delivered to the buyer on the 24th. Poshmark has a 72 hour window for the buyer to rate the purchase. If they don't, Poshmark will release funds so the buyer gets paid. It was well past 72 hours, and I had not been paid and the buyer didn't rate the purchase, so I sent a message to Poshmark requesting to get paid. I got no response from Poshmark. There was a "your payment is on hold," notice at the bottom of the sold listing. I had no idea why. On the 27th, the buyer sent me a message, stating that the pants were dirty on the surface and had soiling in the crotch. I asked for pictures, but she didn't submit any. Yesterday, I got a notification from Poshmark that the buyer opened a case for dirty pants. I sent Poshmark my pictures of my listing, but they didn't respond to me. They approved the buyer's case. The pants were CLEAN when I listed, sold and shipped them. The buyer ruined them, so I cannot resell them. Poshmark is practicing unfair business with their sellers! The buyer is trying to scam me, and Poshmark is an accomplice to this! #1: They don't communicate or reply back to e-mails, and they have no one answering their phones. #2: They don't release your payment after 72 hours. It was over 85 hours, and they allowed the buyer to open a case and then accepted it 5 days later! #3: Poshmark froze my account without telling me why or giving me prior notice, so I was not able to do anything for over a day!
