Shocking service all round

About 25 years ago we opened a Nedbank account. The issues we have had are as follows A few years ago we entered our profile password incorrectly and the account was locked. Nedbank refused to reset it - we knew the password they just had to reset it. Nedbank refused and indicated that we can use cellphone Banking. This was quite inconvenient but we battled along. About two years ago this was also disabled. We can also not get a statement on our bank card. Every time we need to request a statement via a personal banker and the turn around time for this is totally unacceptable. I have logged 4 requests over 2 days and had no reply to date! How, I ask you, are we expected to manage this account with ZERO visibility of what is going on? The support team are not very effective. Nedbank you don't supply the information, we have no visibility on the account and we get no assistance and you still take penalties if we cannot rectify the account due to your lack of service,

How do we get this resolved!
