I got an email from ***** saying My account was recently identified as being involved in suspected *****. Funds related to suspected ***** were transferred into my account on Friday which was R3500 and Capitec bank didn’t notify me before freezing my account, I just saw the time I wanted to pay for my school fees…and I don’t know what’s happening because a friend asked to use my account to receive money from a client then I cash sent them but now they say its ***** money which I didn’t know cos I’m not involved in any *****ulent activities and the account is the same account I received my salary from
