Disgusted customer services from Sun City

I'm utterly disgusted with the services of Sun City. I made an online booking on the 6th Aug'22 for a 4 night stay at the Cabana's from the 17Oct to 21Oct.'22. I cancelled my booking on the 26Aug'22. Since then I did not receive any refund. I called both the Sun City Reservation and Call centres. I had to wait over 30mins for an agent to answer. The agent email the refunds department and have not received any correspondences. It's been over two weeks and nobody from Sun City bothered to contact me. This is ridiculous. It's strange that for a reservation enquiry they are very eager to assist but to fulfil a service they do not take customer services seriously. I would not recommend making any online booking with Sun City.
