Worst experience ever at Langebaan Holiday Homes!!

We had the worst experience EVER with Langebaan Holiday Homes over December 2015. Firstly after we have paid our 50% deposit and our booking was confirmed, we saw them advertising the house again for that same period. After numerous phone calls to them, they could not be bothered to answer or return our phone calls. Secondly, we received two check in times on our \contract"with them"
