Online ********** account opened under my name

How on earth can someone open an account online and you don't confirm employment?????, on the 19th of April 2019 some devil opened an online account under my name (***** account) and purchased at American swiss for over R5000, how possible is that someone can purchase with so much money and you do not confirm anything. I DID NOT OPEN ANY ACCOUNT WITH TFG, I CANNOT AFFORD IT, SOMEONE IS USING MY DETAILS.
