My Revolut Account Charged €550 from South Africa – How is This Possible?

I noticed that €550 was deducted from my Revolut account when I dined at a restaurant in South Africa. I asked for an investigation, but the bank insisted that the transaction was made through my Google Pay account. Is there a way to make payments from Istanbul and South Africa on the same day, with the transactions happening within a short time period? I'm wondering why I didn't receive a confirmation code if someone had my banking details. Wow, the bank really dropped the ball on this one.
