Standard Bank customer if you want change pay R415 to get change for R1700 and R175 to get small change for R10

I'm a customer of Standard Bank for longer than 30 years. Every month for the past 5 years I will go to Standard bank Three Rivers Vereeniging to get R2000 change, this is for my Domestic worker and Gardener wages and they asked to be paid in smaller notes. This morning I went to Standard Bank Three Rivers, the Teller was busy helping a customer with foreign exchange, the next moment one of the staff members (Monica) interrupt the Teller to ask questions about bank business and a zero that must be in front/ back of an amount and that the Teller must "google" it. Very rude of a bank staff member to interrupt a Teller that's busy with a customer. When this Monica turned back she saw the money in my hand and ask me if I'm their for change and I said yes, then she said I will be help in a few seconds. Well there was only 1 teller and I waited for almost 20 minutes, no big deal right. When it was my turn and I ask the teller for change she ask if I'm a account holder, I took out my bank card and show it to her. Then she said that if I want change for R1700 the cost on it will be R415 that I must pay xtra. I couldn't believe my ears and said to her it can't be, she must be joking. She said yes that's the charges that I must pay if I want change from the bank, so I ask my money back. I ask her if she could give me small change for R10 so I can pay a car guard. She said that will cost me R175!!!! What a shock!!! I went to the managers office and said to her this is unacceptable a pathetic that customer been charges to get change. No where in the bank is a notice of it, I did not receive any communication of such fees and the reception at the door that took everybody's name and cell number didn't mention it either!! The Manager took me to the Monica woman that was sitting at a desk and yes I was upset but she was not friendly at all. The manager told her that I'm not happy and she said that's how it work , you have to pay when you want change, we only give change to business owners free of charges and this charges was implemented a long time ago. So I said to her well not that I know of because I was in the bank end of Feb and I got change with out charges. With a very rude attitude she said to me, that this will be the last time that they will help me and she walk to the teller with me following her. She said to the teller: "This is the last time you will help her with change, never again" Really how much service fee, interest and bank charges did Standard Bank take from me over the years and now they will not even give me change on money that I with draw from their ATM. Well if Standard Bank doesn't want to help people with change put up signs at the door and tellers of what the charges will be on any amount that you want change for. If Standard Bank doesn't want to have customers inside the bank, make the ATM's that you can get the required change that you need. This is ridiculous that me as a customer of Standard Bank for over 30 years can't get a service that I'm in need of in the Bank. .
