Nedbank's poor investigation

As much as it been over 5years since this incident but i wasn't fully satisfied with their investigation after my nedbank card was swallowed by FNB atm in durban.It was black Friday early in the morning when i went to widraw money for rent,when i got to the atm there was a two ladies infront of me who were complaining about the same Nedbank ATM which swallowed their friend's card on the previous day so i decided to withdraw on FNB which was close to Nedbank ATM.After inserting my card then punched my Pin when the FNB screen had to give me an option to choose the amount i want to widraw it just flashed back to the main menu as if i didn't insert the card.I tried calling the Nedbank customer care since it was 05:40 no one answered up until i told myself that I'll go to the branch when they open.Surprisingly around 06:20am i received a notification that state that 1500 was withdrawn in my account.when i arrived at the branch(Nedbank branch in Smith street In Durban) it was 08:31 just after they opened i received another notification which state that cashback of 2500 has been withdrawn again in Kwamashu,when i went in to notify the tellers they gave me a phone to block my card while i was on the phone another 2500 went out then 1000 again while waiting for an agent to pick up the call and i was left with 200.43,While explaining to the lady the last 200 went out so she she blocked the card i was left with 43cent and i was told to comeback after 7days since they will investigate.On my arrival on the 7the day i was told that someone saw my pin and stole my card but the shocking part is that i was alone on the ATM and my other question is that what's the reason of setting a limit because my limit was 2000 for widrawals and 1000 for swiping so what's the purpose of it since it was bypassed and still never not my money back.The reason why it took me this long to write this review it simple because i didn't know know the right platom and part of decided to let it go but i cant just let it go without any clear answers and that's the last time i used that bank account and i always advise my family members not to even think about Nedbank because it simply shows that all they care about is their interest,profits not us as bankers
