R13000 out of my account within 9 minutes.

In Germiston. By Tops Spar, theres 2 ATM'S. I tried to withdraw R400. The 1st ATM masjine took my card and pin. No other buttons were then working. So I press the cancell button, and got my card back. Then tried the other atm next to it. Took my card and never asked for a pin. I thought my card was swollowed by the ATM. As I stood there I made myself a ewallet because I urgently needed to put petrol in my car. As I was still trying to google the tel nr for lost or ****** cards, and as n was busy to stop my card, someone was withdrawing R3000 and swiped my card for R9500. I went in the bank in Lambton the same day and filled in all the forms that the bank needed. We pay ATM fees but instead loose money thats budgetted for my payments and family. After numeas calls they rep**** that they dont take any responsibilily for my loss. Its all luckilyon a shops camera footage that the owner showed me. What should I do and how do I vo to work in this mattor? I think my first step will be to change banks definately. Please can someone advice me how to start this unfair process. ********** ********** 732. Ive got all the proof
