Disgusting, appalling Service

I'm 88 years of old. I called Nedbank to give me information on my Just Investment account. After 20 minutes no-one could assist me. I was then told I had to go into the branch to sort this out. I told him I couldn't and that I am very ill with cancer. He then told me he was going to get assistance from a branch, and he put me back to the call centre where he expected me to start all over again. I'm not sure how a Customer Care person can treat an elderly woman with cancer like this. I am appalled. I would like to know what has happened to my Just Investment account and I would like the call investigated and the person who did this to me explain how he could.
