You'll get your money back. I'd go as far as saying that if the bank genuinely wants you to decide fast, it's not to protect you. It's to protect itself. Shenanigans about "do it fast or they'll take more" are bullshit always. The bank is on the hook, not you. So never do things in a rush, take your time to verify yourself that money indeed disappeared. There. is. no. urgency.
Sense of urgency is one of the best ways to make people do bad decisions. Salespeople use it, scammers use it. Nobody who is trying to be helpful will come with a story "that needs to be fixed now!!!".
If you still want to be safe, and you use a debit card, have 2 accounts. One with the bulk of your money without a card associated with it. One with the card associated with it and no more than whatever you spend in a week. If you use a credit card, it totally doesn't matter, it's the banks money, not yours that they'd steal.
So whenever you find yourself in a situation where someone wants you to decide something fast that you didn't know about and isn't a direct threat to your life, don't do it. Think about it first.
It's impossible to keep up with all the scams, but if you stop to think and never take rash decisions you don't have to. Slow is safe.
