binance charged me $ 200 for no reason?

Hi today when I was shopping for groceries my card was denied, this was very strange because I knew I had money in the bank. when I looked at my expenses, I see that Binance.com has deducted 200 dollar from my account, I am extremely worried about why this has happened because I have neither bought nor transferred money from Binance recently. this transaction isn't even visible on my history on the Binance website. maybe theres a natural explanation to this, but I would appreciate if you could help me understand why this has happened.
