Nedbank blocks my account after complying with their request

Nedbank sends me a sms to confirm my details failing which, my account would be blocked.

Detailed steps are provided on how to execute on the app, which I follow through and I receive a "success" message, and all is fine for 2 or 3 months, when I start receiving the same message again. I ignore it as I have already confirmed my details as requested, and they now block my account.

Following this, I go back to the app and reconfirm all that I had already confirmed, and I receive a message thanking me for my action and confirming that my account will be unblocked within 24 hours.

4 days have since passed and my account remains blocked. I am livid as I work longer hours than Nedbanks operating hours and cannot go into a branch. Why am I told everything is OK, but they still block my account?

No information has changed - there was nothing to confirm anyway in the first place?????
