No customer service

My Father and I have an existing Trust account with Nedbank, been active for nearly 20 years. My father also banks with Nedbank, his personal account and the Trust account is on the same online profile. All we need is to have 2 online profiles, one for the Trust and one for my Fathers account. We went to a branch to have this done, staff not sure what to do. I have mailed complaints, also no luck. This is very unprofessional and not customer friendly at all. Please can someone help here?
