Poor systems and customer service

I changed my name due to divorce. I provided the original divorce decree and new ID document at a branch. Nedbank changed my name on their system but after more than 3 months have not updated the name on my bank statements and have just reissued me with a new bank card with my previous name. It took me three calls with their call centre for the agent to actually assist me. I will now wait and see if the cards I have requested as well as my next bank statements will have the correct details. What a massive inconvenience for something that should be automated.
