********** on my credit card within African Bank branch

I have followed all protocols, when I call Jabulani Kabini, Tshepiso Naale and Nadette Rappard no one answeres. Nadette responded with one line letter and say the case is pending, Its being 3 months waiting for a feedback from forensic with regard to the outcome of the investigation. I'm paying the interest of money that I didn't spend and the credit card is blocked, African bank service is very horrible. They don't care about their customers.
