Useless

I went to jabulani mall fnb to deposit cash and when I when to the teller she told me I must go deposit my money at the ATM. I told her I never used their ATM to deposit before and she told me someone is there help me,the lady who help me was not friendly at all and didnt even finish helping me...when I got home I realized my slip says there was an error meaning my money didn't go through.when I went to go an complain about this didnt really get a satisfying help I even had to ask for the footage and I was told to come back after two days. I'm not happy about how we being treated as black people at the townships mall. And I would really like them to change their attitudes towards their clients...ive lost money and it doesn't look like I am gonna get it back. Please help.
