Nedbank has lost the plot

I have had a business account with Nedbank for about 4 years. I do not receive regular payments into the account and particularly during lockdown, I have not received payments. I received a payment into my account in December and have tried to transact on my Nedbank account but the system said "Account valid; Status invalid" which means nothing to me. I contacted the call centre who told me that it is inactive so I can't transact against it "to protect me" and I now have to go into the branch to reactivate it and have to have proof of payment for the payment that I received at the start of December. So they willy nilly block my account and cause me massive inconvenience when I want to use MY MONEY!?

WHAT UTTER ******* IS THIS?!
