Bad service charged for viewing the place.

We went there hoping to spend the day. Greeted by a friendly Big Guy. I asked can I go and see the place he agreed. Paid as I thought we would stay. Walked down and realised that we could not go down with our car, I came back and asked he said it wouldn’t be possible. My friend has back issues and we could not walk down the embankment. I then said to him it’s ok cancel and rather give my money back as we had just been there for less than 10mins. He tells me he can’t give me a refund of total amount as he gave me a band that we had not yet used. We paid R160 and were given back R100 for viewing the place. Bad service.
