No service at all!

So on the 17th of July 2018 I left work early to attend to my appointment that banker (Marvin) had set up for me at 15:00. I get there and I wait to get attended to. It’s 30minutes later and the lady walking the floor comes up to me and asks if she could take my details so they could set up another appointment because it doesn’t seem like I’m gonna to on that day. I left the bank very angry at 15:50 because I was still waiting. I couldn’t even finalize my business account application. I thought since I can’t just walk into the bank to apply for a business account , There would be a reason something is called and appointment. Very disappointing from Nedbank
