A Scammer in poshmark! my credit card was stolen and abused!

Hi It's my first time being a seller in poshmark. (I never sold things in apps). First, @jenbcute he commented saying that he is interested in my T shirt but his app gets stuck, can't see the clear pictures, so he left his email address, asked me sent pictures by email(this comment was deleted after the fraud). I sent pictures. Then,he emailed me again saying that he had already paid it, he even told me I would receive an email to complete the transaction. I received an email with the poshmark logo. Actually it's a fraud email. Its email address is not official. The fraud email was with poshmark logo and, the email said if you want to complete the selling process, click the attached link. Click the link and it redirected to a chat window, a "customer service associate" (actually a scammer) asked what item you sold? I answered the item name and she gave me a link. click the link, there are blanks for my credit card information. It says filling out your card information to accept buyer's payment. I've been diddled. I filled out my card number and CVC. Then the "customer service" said the card doesn't work, and she asked me to try other card or fill out my friends/family card. She said I must filled out a valid card, otherwise the buyer's money would be blocked and my poshmark account would be also blocked. She was even trying to stole more credit cards. then I was charged 183$ by MONODirectFJ3, account from Ukraine.
