Utterly disgusting customer service

We are having the worst experience ever with the *********** service from the staff / sales consultants at Dream Resorts and Hotel. I purchased Unit 80 at Mjejane Bush camp around 5 years ago and the Unit is completely paid up. Out initial week was 21 June to 28 June annually, however, after covid, Dream Resorts decided unilaterally to change our week to 04 July to 11 July annually. On 03 February 2025, we made a booking to occupy our unit this year, on 25 March 2025 received the confirmation from Mjejane that all the levies are paid up and in good standing. On May 2025, we received a confirmation that everything is in order. On Tuesday, 10 June 2025, I received a phone call to say that we cannot occupy our unit as it has been space banked and they have already given the unit to somebody else. This is completely unacceptable, so started a myriad of email communication back and forth. I requested information from them with the time frames that the booking has been made and also a timeline with regards to the space banking as well clarity on how can a unit that has been purchased under an Ownership Block just be given to somebody else without notifying the block owner. They refer me back to an email in February 2024 where I requested my login details to their portal (for whatever reason, they believe that this has army relevance to the present challenge). They further went on to say that I space banked this in November 2024, but I cannot find such a timeline. The only dated document that they can provide is March 2025, which they are completely overlooking. In addition to this, the only response that they can give me is that THEY ARE REITERATING THAT WE CANNOT OCCUPY THE UNIT AS SOMEBODY ELSE HAS BEEN BOOKED IN THERE. Now, even more interesting is that I have 19000 points available as well as I have space banked the last 3 years. Then, to add further misery, they have decided to add another week 26 June to 04 July to the whole story which I know absolutely nothing about and on that week, it says space banking undecided. As i mentioned, I have no idea where this suddenly popped up from. My email communication was getting me nowhere, so I decided to call the lady (at 13h50 on 17 June 2025) that has dealt with our account in the past, and she admitted that it was an error on their side and the week was space banked. But still, no timeline as to when it was space banked. The only dates I have was March 2025 AND the booking was made on 03 February 2024. I have requested the contact email for the Managing Director, which they are refusing to give to me. This week has special significance as it is my dad's 80th birthday. The manner in which this is being handled is absolutely unacceptable to a point where I feel like I am being bul****. If the lady did not admit that it was their error, they made it seem like I am a villain. This is outrageous. This is NOT a free gift from them. I purchased this unit and PAID FOR IT!!!!! I need honest answers now please. Not customer service executives that do not know how to deal with people.
