Nedbank Pathetic Repeated Experience

I app**** for a credit limit increase of 10k and Nedbank instead issued me with another credit card to the value of 20k . Since I received the card it didn’t work and when I called the Nedbank call centre I was told they offline and cannot help.Hence I had to compromise and transfer funds to another account using the app. If they were offline when I contacted Nedbank the professional thing to do is return the call when you back online which never happened.Fast track to yesterday, I went to the Nedbank The Glen and again they couldn’t assist and referred me to call centre. Tried calling 3 times and consultants couldn’t hear me and on 4th attempt I got thro however when I tried closing both credit card accounts I was told that there is pending transaction on the 1 account and that we have to wait cos the vendor needs to process on their end.So net net account cannot be closed yet the account is paid up . I disputed then the consultant said she’s referring me to another department but cut me off and never bothered calling back . I’m sitting with an unresolved issue and paying Intrest on a paid up account. Nedbank your staff are unprofessional and need training on what customer service means. How do you want me to use a credit card that does not work .Sorry to say your institution is pathetic 😳No wonder you have such a poor trust index
