No hot water for luxury accommodation

We paid an exorbitant amount for a 2 night stay which we were happy to do only to find that the geyser had a timer yet never went on. We arrived late so first night assumed it's warming up. Early morning we advised agent in writing that the water is still freezing. That afternoon electrician came out and said he can't stop timer as must get into roof and needs new thermostat. This threw our day out completely as waited for him. Sent message through sat and Sunday complaining as we didn't shower or bath out baby (missed 4 showers each the weekend. The owner refunded us R300 per day for inconvenience even though they advised we would be refunded. After what we paid to say compared to the measly amount refunded we feel ******.

No inspection with is was done and their clause of latent defects cannot include no hot water. We would expect more from a caravan park. I would never recommend anyone use this agency as they don't offer what they promise. We paid for a working house and walking distance to beach & received neither
