Dear reddit, I got a time share presentation with a deposit before I knew what it was. How can I get my deposit back and avoid the presentation???

I was on Hilton call today trying to change my hotel reservation and they put me on a call with a sales rep to earn some points, so I thought why not. She came on the line and kept telling me, convincing me, and lying to me that the sales presentation is great and everyone is doing it. I later found what they do to people in those rooms during presentations and I feel disgusted and I do not want to go. However, she already took my money from me as a deposit, how can I get it back and avoid this thing forever?
