Inability to receive SMS notifications of account

I have been trying for months now to receive reliable SMS notifications of movement on our current and credit card accounts for which I subscribe and pay the fee. I have a collection of reference numbers and the call centre tells me to go to my branch and the branch tells me to phone the customer care centre. I am now at a loss of what to do to get what I am entitled to, and unfortunately must say that we have banked with Nedbank since it was Netherlands Bank of SA and we are NOT content with the lame excuses offered from both sides with this kind of service.
