This is weird

I won an auction for a watch. A cheap watch, around $8. I was the only bidder. I remember the lady congratulating me on the win. I went back to watch the video receipt, like I always do. I like to screenshot the item and run it through AI and get some info on it. A week goes by and I figured I would check the tracking. There's nothing there. There's nothing in the refund section either. I buy so many things, at this point I can't figure out if my credit card was charged or not. It's like it never happened, but I know I bought it. Any idea?
