SAA debited my account with no valid reason

Today 06.06.2025, R1785.69 was debited from my account. My bank account was also deactivated, I discovered all these when I was purchasing in one of retail shops that my account was deactivated. I had to investigate then to find that it was frozen. Shortly after I called Tymebank,I was told that my case was logged and is under investigation. I then called South African Airways and they took me back and forth until i was advised to send my names and proof of the transaction made and thats when i received an sms from my bank that the issue was resolved and therefore a debit transaction of R1785.69 happened. I still don't know what is going on and what is the transaction all about.what I just want is my money
