Nedbank CEO need to be called to account but you cant reach him

for more than two years now I have not been able to get nedbank to sort out my login ID details. I have had initial contact and then total silence repeatedly for two years or more now, yet all the adverts they use tells you how much nedbank values you as a customer. This is the CEO's responsibility, he should have a handle on whats happening in his business but I am sure he will receive a huge bonus in December derived from my banking fees!! hell man what has happened to service?
