Nedbank Lack of Response.

I received a call from Nedbanks call centre enquiring about how their service is. I decided to tell the caller about the trouble I have been having just arranging a meeting to discuss the study loan I have, for my son, with Nedbank. This was on the 17 January. To date, and numerous mail later....not even a response. Mails have been sent to [Email Removed] [Email Removed] and [Email Removed] Nothing. All I want is a meeting to discuss the way forward with a person from Nedbank who can make decisions on the student loan I already have with Nedbank.
