Standard Bank does not value long standing relationships with customers

I cannot believe that I have been a very loyal customer of Standard Bank since 2003 and when I want to open a professional account they have an issue. I mean not everyone is fortunate enough to graduate straight after school. Some of us had to work very hard in order to send ourselves to school and only later we are able to graduate. Now just because I am not of their ideal age I cannot get the professional account even though I have been their customer for so many years? It is such things that make me not want to ever say anything nice about a company, same thing that makes me not ever want to recommend it to anyone else. I am disappointed
