Poor Service at Rustenburg Mall Nedbank

Nedbank Rustenburg Bank is one of the poorest services ever I went to the bank around 13:55 to Bank bulk money, the cashier lady first tell me she's close, I asked her how if they let me in. The next she says she wants to cash out so I must come tomorrow, I had to explain to her that I'll be at work. Then she says she'll assist me after 30 minutes if she's done, I tried to explain to her that I'm on lunch have to go back to work. She insisted maybe I should come tomorrow. My question is: 1. Don't they consider my safety of walking around with bulk cash if she insist I must come tomorrow. 2. Where is the formal communique to inform clients that cashier knocks off few hours earlier, at 13:00 before the bank closes at 17:00
