Bad attitude and undermining

Hi, My sister Nomsa went to open a savings account at Nedbank Maponya mall branch today 07/09/2020, after she waited on the long queue for her turn to come, she was assist by Johannes Morakalla, which he asked her since she was employed why does she need a bank account what would she do with a bank account, and who is gonna deposit money for her on the account and how much will be deposited in her account monthly, so i fail to understand that in order to open a savings account with Nedbank you must be employed cant you just open the account for saving, i am the one who referred her to open the account at Nedbank cause i have good experience with the bank, now both my sister and i we a very disappointed and undermined by the bank, shame on Johannes guy hes got bad attitude and denied to open an account for my sister.
