Poor service from Nedbank

Absolutely appalling service, or lack there off. Credit card was paid off on 06.11.23 and I requested a paid up letter, all i am getting are excuses and delays. They also report the incorrect information to the credit bureaus which in turn affects my credit rating negatively. Isec does not respond to a client. makes commitments and does not keep to them. So glad i am done with this bank. Just wish i can get my paid up letter, but i guess this is going to be an endless fight.
