LINKED MY SONS ACCOUNT TO A STRANGERS ACCOUNT

I opened an account for both my minor children - under my account - now, 5 years later when I'm asked to re-FICA the accounts they tell me I cannot do this as my sons account is linked to another persons account and that person has full access (THIS PERSON CAN WITHDRAW ALL THE FUNDS AS WELL) - The account is linked to my online internet banking (So I never expected anything to be out of the ordinary), but I HAVE NO ACCESS to his account! After spending 2 and a half hours at Centurion Mall branch I'm sent away to Menlyn Maine Branch, where the account was opened, to get the matter sorted. It cost me 4 and a half hours in total to get this sorted - AND STILL THE ACCOUNT IS NOT LINKED TO MY CIS PROFILE - STILL LINKED TO ANTHER PERSON! Seriously FED UP with Nedbank and all their ***** ups - And then the client needs to drive back and forth and spends hours on the phone to get Nedbanks mistakes corrected!! HOW DO YOU EVEN MAKE AN ERROR LIKE THIS???!!!!!!!
