lack of security

***** happening in my card and no assistance. My card was blocked on the 1st Jan 2018 but there has been transaction going till the 26Feb 2018 looking at my statement. I have disputed two other amount that happened when i had zero amount into my account but no one at absa can tell me why that happened. till to date i have not received any feedback from Absa Dispute department which is only reachable by mail. This is how ABSA treat their platinum cardholders?
