Unauthorised transactions

I have been a Nedbank customer for 35 years, since peoples bank time. I am utterly disgusted in the way the bank has handles my affairs recently. I receive a sassa grant and am unemployed.

My banking details has been compromised and there are unauthorised transactions on my account that i am not aware of and have no knowledge of. The consultants at the bank in canal walk was extremely unhelpful and all she said was someone took my money and its gone. I cannot accept that reason.

She stopped my card,. Reissue me with a new card. If i did not authorise the payments from my card, why was my money taken? Why are u not paying my money back? How can i trust a bank that allowed ********** transactions on my account and how can nedbank not take responsibility for ghe money that missing?

I am also being charged for a new card? Why? This is not my fault.
