Defamation of Character

I am highly disgusted and disappointed in the manner i was treated Sunday 27/12/2015 at the bar area, i was called a ***** infront of customers in the bar after pine lake bar lady argued with me and said she gave my change of which she didn't, she was so rude shouting at me and eventually taking money out of her pocket saying she will just pay it now if you know you gave my change why are you giving from your money, and why do you even have money with you if you are a cashier when there is a tip box on the counter, i have reported this incident to Marius which was on duty that afternoon today it is 2 days later and i haven't received any feedback whatsoever. I don't know her name as she was not wearing a name badge however her colleagues name is Nono so she can be asked about her colleague that was so disgustingly rude to me. She attended to customers while she was dealing with me left me there without a word while cashing up ect, total lack of communication, let me wait 15 minutes then another 10 minutes without a word, I am so disappointed that pine lake marina has staff that is so unprofessional and rude. I would like feedback regarding this.
