Nedbank Credit Card Division. They don't exist.

I have a credit card with Nedbank. I use it regularly and my account has never been compromised or mal-administered. It has been more than a year now that I have not been able to access or manage my account via the mobile app or internet online banking, even though I am able to transact using my credit card at ATMs and vendors. I have reported this problem multiple times at branches or via the various helplines. I ALWAYS get told the same old story. "The credit card division is separate and I need to contact them directly for assistance". This results in more phone calls and e-mails, either from myself or poor staff at the branch trying to help. To date I have not been able to speak to a single person involved in the credit card division. I am beginning to doubt they exist. I have twice received feedback, (from branch officials no less), that my profile has been suspended and I need to reset it. The procedure they give me to reset ALWAYS fails, even when Nedbank staff try it. It's quite embarrasing to them. I am then told someone at the credit card division, which I doubt exists, will now have to assist me in resetting my profile. This leads to more phone calls and mails, ALWAYS without result. I recently used the Nedbank complaint e-mail procedure. A representative contacted me with assurance that some-one would contact me to help. This was more than a week ago. PLEASE, CAN SOMEONE FROM THE NEDBANK CREDIT CARD DIVISION CONTACT ME TO SORT THIS MESS OUT. That is if you exist.
