Very Poor Customer service from Nedbank sales call centre

A representative of Nedbank service contacted me +-2months ago enquiring if I would be interested in one of there services on my account, we then went through all the hoopla and all doc's was sent from my side, but i never heard from him again. I phoned customer care, being scared that this was not really one of their people, and now I have sent all my personal doc's. They confirmed that all was legit and transferred me to the department where I explained. The gentle man told me he will find the guy I mailed my doc's to, he came back saying the guy does not work in sales anymore thus my stuff expired, but he will assist me, i will thou have to send all the doc's again, which i did, I followed up everyday for almost for a week, and he just kept saying he is waiting for doc's I have to sign from another dept. No feedback other than that, now when I asked again, he told me that my application expired again and we have to do it all from scratch. I asked him why he did not follow up, and why did he not receive the doc's, no reply. I was just asked it I still want the service so that he can phone me again, on which I asked him just to find out whey nothing was received, Till today, No feedback, no Call nothing. This is not acceptable customer service. I have to follow up, and nothing was done from his side. This is Poor customer service, no follow up, feedback, no reply beside for do you still want it or not, basically. This is definitely not acceptable or in line with the kind of service Nedbank sets themselves out to give.
