Nedbank not taking major client issue seriously

I opened a business account with Nedbank Hartswater during 2016 but have not really used it until 2019. I have only been paying bank costs on the account of course.

This year my business at last started operating but to my amazement I was unable to make payments through my online banking with Nedbank. Various interactions with numerous personnel brought different answers such as "The account was for some reason suspended" (no one could say why) and I needed to sign documents to get it active again, that did not work, next they had to issue me with a new token (once again not explaining what was wrong with the previous one), after finally getting the new token to work the account could still not make payments, this time the answer was the account is "dormant" and once again I had to sign documents to get it lifted.

This whole process started on 29 March and we are now at the 2nd of May, yet still I can not use the account on which I have been paying monthly bank costs. This is extremely unacceptable and I keep getting answers that a different department has to fix it.
