I'll treated because I'm black

Yesterday I called the standard bank customer line to make an appointment for a new business acc I want to open with them they told me they don't do appointments they deal with walk ins and I should go to nearest branch I went to STANDERTON STANDARD BANK and found an indian woman named ZORAH BANOO KHAN who deals with new business acc and she told that she doesn't deal with walk ins I should come back tomorrow morning I did just that and when I arrived this morning she told me that they are offline I should come back at 2:30pm I did just that again and came back at 2:25 she told me that I didn't hear her well she said I must come at 2pm now she can't help me because she's already helping a client that came in at 2pm my question to her was if my app was suppose to be at 2pm how come are you helping a client that came in at 2pm without an appointment and she started shouting telling me that we "blacks" have a tendency of African time and it doesn't work that way on the cooperate world if I want to be helped I should come back on monday and she won't help me with such a bad attitude I should go to another bank and it's not the 1st time she's turning me away...in Nov 2017 she told me that I cannot open a business acc if my company doesn't have any active project that woman is ****** and rude standard bank should do something about her as many people are complaining about her
