Slow service

I went to Festival mall nedbank to ask about my options in investment and to my surprise the ladies who is supposed to ask me where do I need help she told me about the investment available but she didn't have the right information and when I mention that I need to know how much interest I'll be getting she then said ok let me write your name to be helped by the right person. My question was why did she even offer if she's not fully trained to do that?she wrote my name and waited for the sales person, funny enough she went and spoke to the available sales lady and I can could count three ladies sitting there and chatting while I am waiting and there was just one person infront on me but we waited there for about thirty minutes with no help and I decided to leave and seek help somewhere. I always get help from Nedbank but mybe it's just this branch service needs to be looked at.ill never go to that branch anymore.i didn't ask for 32days!mybe she judged me and thought I'm one of the 32days account people because that is what she actually wanted to sell me.
