Bad service

Bad service from The Fun Company in Menlyn. We bought drinks with Friends Sunday evening. A lady by the name of Alletta served us and looked very Intoxicated.We asked her for a receipt and she said that there is problem with the printer and the Manager will come to assist.She then gave me a wrong receipt. Told her it was not mine, she then took it back. She charged us R224..After paying I insisted on a receipt again and miraculously it appeared and I was overcharged with R10. When I asked about it she send her Colleague to give me R10. No apology whatsoever, I then called her and she started shouting. This is really disappointing and makes me wonder how many People are ****** by the likes of Aletta
