Pathetic service from a Nedbank Consultant

I am not happy with the poor service I'm getting from Nedbank or should I say the consultant I am dealing with by the name of Bester Shereef at Tygervalley Mall Nedbank in Cape Town doesn't seem to care. I went to the bank on the 24th February to sign for this overdraft after I sent a complaint he then called me to say he was supposed to send some documents to the overdraft department which HE DIDNT because he was busy but it's now done I should go to the branch and sign my overdraft have been approved. i went there on the 24th February to sign and since then it's quite nothing reflects on my account and I sent him an email asking how long will this take to reflect on my account which he didn't reply to. Highly possible that he didn't even submit those documents because this is not the first time I make such an application at Nedbank with a very good consultant and everything was done quick. Nedbank will lose clients if we deal with people like him. Currently I am so not happy with the service I get from Nedbank as their client.
