How do I get my giveaways?

I won two giveaways from the same page on tiktok live and they never sent them. They also ignored my comments on live chat and they've ignored all of my messages. They're being super shady and I was wondering if there's anything I can do? I contacted support but they sent me on a wild goose chase. It's not that I want the giveaway that bad but it's the principal that I won twice and they're not following through.
