Managers don't acknowledge or respect punters

I put my Card in the machine and then I put a R100 note in as well and the machine goes into error. I go get the attendant who then informed me that I have to inconvenient myself and go stand like a begger at the cash desk with a A4 sheet if I want my R100 back. I Then go with him to the desk to process this manual payout request. He calls Jerome Oliver who doesn't even acknowledge me at all to authorize this transaction. I'm upset that it is acceptable that a manager doesn't need to acknowledge punters in your establishment. maybe it is because I'm a person of colour and not white that I was subjected to this kind of treatment. Anyway I will do what I do best and that is to spread negativity about the treatment I receive from management at Grandwest Casino. Nowhere did anyone on of your team members apologize for the inconvenience caused by your equipment that is supposed to be kept in optimal condition at all times as per gambling board regulations.
