AMEX credit card

I have an AMEX Credit Card through Nedbank. Last year I'd struggled severely to get my retrenchment claim paid out. Ever since, although I receive an account, I'm not allowed to see the account details and merely receive an amount payable with no breakdown of the account. I have visited Nedbank Tygervalley in order to get an account statement, but was told I am no longer deemed a client and therefore have no access to any account details. Having been retrenched, my insurance and retrenchment information should be made available to me under the NCA, insurance legislation and banking act. I have noted a previous time that my information is being withheld from me and Nedbank has responded that I am not allowed to view my account as I am no longer eligible for credit and have been retrenched. Without a breakdown of my account, however, I am not sure how my insurance, interest or other fees had been adapted by Nedbank - although restructuring and amendments to insurance, credit and account information is a requirement after retrenchment. This is my last email to HelloPeter before I approach the NCR, Ombudsman for banking and Insurance, as Nedbank has willfully obstructed me from managing my account for months.
