Century village parking area

I went to the parking area and they had just put in a boom we were let in manually we got no ticket they said that the first 30 minutes free and then R 10 anhour but when we got out the attendant charged as R20 as he said we were there for over 2 hours but we were there for just over an hour he overcharged us yoyu can only tap your card and the attendant was aggressive. I advise people to think twice before you go there.
