No Overseas Assistance

I have tried to get hold of someone at Nedbank to close my account. I moved to UK in Feb 2022 and no support from Nedbank when I have had queries. Now I want to close my account. They are happy to take their maintenance fee every month though. I have tried the chat when logged in to my online banking, but there is a time limit when you logged in. I was just informed to contact my personal banker, which I do not have! I then emailed them and no response. My father, who has Power of Attorney was told he can't do anything. I have extra money in my credit card account but as I am not in SA and have not received my new credit card, I am not able to access this account on my online banking to move funds out. Does anybody respond? No. We are now going on month 4 with no response. Disgusting!
