Hi, my name is Edwin Malatji. I have an account with capitec bank and i have being with them for more than 10 Years. my card was swallowed by an atm at Diepsloot Mall, after some few minutes, i received a message that the amount of R3000 was withdrawn in another atm at William Nicol Johannesburg. when i open an capitec app to stop the card R2000 again was withdrawn at the same address .I ran to the branch in Diepsloot mall and explaining the problem, they told me they will call me after 4 to 5 working days. when the lady call on Friday afternoon i was in the taxi could not able to talk to the agent however i manage to go to the branch. so they call and one of the lady from capitec had office told me that the problem have been handed over to it department and they will come back to me but they never came back. i called them and they said they cant able to refund me. i am very sad, not happy at all. i am thinking of changing the back because my money is not safe. capitec bank i need my money back please.
