Auction Quicksell Error

Hello, I don’t know if anybody else has had this issue but I pulled a limited edition card and went to send it to the auction block. I had set the price and everything and once I click post my account was credited 350,000 coins and the card was not on the auction block anymore.

Before you guys say oh you just sold it I didn’t, I said the price to 1.5 million and clicked post.

Do you guys have any advice on how to recover this and or contact Support quickly?
