Tanglewood Nature Estate and Lekkeslaap

My husband and I reserved a camping space at Tanglewood Nature estate for two weeks. The reservation was made from 13/03/2023 until 27/03/2023, (outside school holidays). We already booked the accommodation on the 22/01/2023 and paid the deposit which was 50% of the booking, to confirm the booking. On the 26/01/2023 I was offered to progress in my career which I have been waiting for a couple of years. The only problem was that a had to start with a course on 20/02/2023 which will last for 5 months, which made it unable for us to go on vacation for the time we have already booked. We immediately contacted Lekkeslaap to postpone the dates, because we booked the accommodation through them. We did not want to cancel the reservation only to postpone it for a couple of months. They told us that Tanglewood Nature Estate said that if we are not going to use the dates that we initially reserved they will see it as a cancellation and will only refund us 50% of the money we already paid. We even contacted Tanglewood themselves to explain our situation and to confirm that we only wanted to postpone the dates and not cancel our reservation, but unfortunately they did not care at all. We are very disappointed with the outcome of their decision and would never advise anyone to use Tanglewood Nature Estate as this is not about the financial loss we are taking but rather the lack of understanding and sympathy shown by Lekkeslaap and also the owners of Tanglewood Nature Estate.
