Nedbank fails to help!

I have been battling since the 16th of October 2018 to get the hold on my credit card lifted after I have been retrenched. The bank has requested all sorts of documents, from bank statements to an appointment letter from my employer. Everything has been submitted, still they say they can't lift the block unless three months' salaries are deposited in my account. These deposits show clearly in my account, I even highlighted it in yellow before submitting. It clearly shows that whoever is in charge of this department hasn't even made an effort to look at the documents I sent through, as requested by the bank. This is a disgrace especially since Nedbank is the most expensive bank in SA. I don't understand why I have to go through this effort to be able to make use of my own account. This is a disgrace and also the reason why Nedbank will always be the second best bank. It just reminds me why I moved bank in the first place. I had to make numerous phone calls already, but to no avail. Do I have to go there and do the job for the Nedbank employees - it seems that is my last hope if I want something to be done. I raised a complaint with the Customer Complaints department on the 25th of October - nothing!!!!!!!!!
