Poor customer service

I was at the till to pay for a skirt ,the cashier didn't bother to greet r say a word to me.I handed over the skirt after which I gave her my cards, Once she was done with the transaction she slammed my cards on the counter. I then asked her why she slammed them instead of giving them to me in my hand,she then refused blatantly and attempted to shove them to me on the counter.I asked her to call he manager and I told the manager what had happened,he then asked her to apologize of which she blatantly refused and all she did was to entertain other customers in the line in a different language which she thought I didn't understand. I am very disgusted at the way I was treated by this cashier.
