Nedbank service is non existent

Extremally poor service from various managers and staff. Trying to add two users to our company profile since 23 May and to date nothing has happened. They reject the form I resubmit as per their request then I get told it is a duplicate submission. I cant submit on a new number as it says a form already exists on another number. Needless to say nothing has happened since 23 May. Sent official complaint to Nedbank - nothing, sent complaints to various managers, still not resolved. I cannot believe that something so simple cannot be actioned by Nedbank.
