Unresolved matter prolonged

I am very unhappy with the service I am getting from Standard Bank (VAF), it doesn't seem like the staff are on the same level with what they tell clients, because one agent will say something and the next agent will say another. I need my matter sorted out! I have been sent from pillar to post trying to get the matter sorted, I have involved my bank as well, and I have spoken to numerous call center agents in different departments for over a month about ONE issue. I was advised that the team leader will give me a call, days later that still hasn't happened, numerous emails with feedback required have been sent to agents and NO feedback still! I am fed-up with repeating myself time and time again to every agent about the same thing. It really is tiring.
