No resolution to ********** transactions commited on credit card 6 months ago!

My father had ***** committed on his Nedbank card on 9 March this year. They were in Durban when within a few hours the ******* placed 4 Uber Eats transactions in JHB and purchased two Kalula air tickets to the amount of R1,430.93. He reported it immediately to the ***** department, put a stop on the card and for 6 months, nothing has happened despite emailing and calling the ***** department, our personal banker and the client services department. Now he is being charged interest on this account which has been settled apart from the ********** amount, plus they are now saying that he will be reported for non-payment, maybe even black listed. I'm not sure anyone knows how to give good client service at Nedbank or perhaps do their required job. He has had personal and business accounts with them for over 40 years. At my wits end, I'm trying Hello Peter to see if they actually care about their self-image more than their clients and to try and help my Dad of 75 bring this to a close so he can stop stressing.
