Reporting a *****

I went to an atm to withdraw money then my card got stuck in the atm, i couldn't proceed with transaction while the card was still stuck in the atm tried cancelling the transaction but it didn't. Few minutes later i received messages stating that the is money withdrawn from my account while there no money coming out from the atm. First R1500 was deducted them few minutes later R1799.97 and then lastly R92 was deducted. My outstanding balance was then R23. I called nedbank to find out what's going on they said they will take 3 weeks to investigate this, they didn't even give me a call reference so i know who to call when i want to do a follow up. I called them again to ask for the call reference, they said they will send me an sms with all the details i will need when i do a follow up but i haven't received the sms.
