Refund request

We paid for Kruger trip on 7-9April2023 and then today,3days before the actual trip the lady says there was an error with the date which was not communicated with us and when we ask for our refund,the lady is telling us that we have no choice but to join their next date of the 28th April 2023.We paid R19 630 and we want it back as we have no leave and no enthuasism of using them anymore as we have experienced their unprofessionalism at first hand as the lady was busy denying the date they gave us,fortunate we saved the chats and the first proof of payment which was sent to us.
