Unfair Contract Agreement

We made a booking accomodation at Tenbury Oceans Apartment, trading as Oceans Escape Durban for 18 people on the 02 February 2022, to be accommodated from the 15-09-2022 to the 19-09-2022. 2x 8 sleeper apartment, we were involved for an amount of R19 400 incl of once of admin fee of 500, depature x 2 of R500. A deposit of R1000 was paid to secure the reservation. However, on the 28 February 2022 then we had to cancel one 8 sleeper,however we changed to 4 sleeper instead of 8 sleeper apartment, meaning that we only had to be liable for 1x 8 sleeper and 1x 4 sleeper apartment and R500 was charged for cancellation. The total amount then became R16 700. The consultant by the name of Trish never advise or communicated to us and gave a breakdown of the 8 sleeper and the breakdown of the 4 sleeper. On the 3rd March 2022, we paid R2 000 for the reservation and a notice was sent to notify that the 50% does not cover the 2 apartments. We communicated with the consultant on the 5 Sep 2022 due to unforeseen circumstances of the guests not being able to travel because of family issues to cancel the 4 sleeper that we booked, we were told that the balance outstanding should be paid. As per the cancellation clause, it states that there won't be any fee that will be refunded but which is fully understand able. Our concern now is that, the consultant should reconsider the whole amount of R14 492 which has already been paid as per invoice received to date. We are not happy at how this whole agreement is handled because now we were advised that a balance of R2 208 need to be settled(this amount includes the initial booking of 1x8 sleeper and 1x4 sleeper) Is this fair for customer to be charged such an absorbident amount after such an amount of R14 492 has already been paid?? What we are pleading and have request the consultant is to re-instate our cancellation of the 1x 4 sleepers apartment and the consultant is refusing to hear our plea, yet we are willing to pay the balance of R2 208 on the 06-09-2022 so as for us not to loose the full amount that we have already paid.
