Terrible customer care service

I made a booking for lunch at Eleven tribes”Zimbali lodge” @12:00 with my friends on the 22nd of March 2026 , there was 11 of us…..so the entrance fee R50 per person which means we paid R550 and that amount should be subtracted from the bill but that they didn’t subtract it..we paid the full amount….we told the manager and she said it was a mistake she will refund us ….since it was a Sunday she said she will call me on Monday morning but she never called…..I called the restaurant 4 times but every time I call they always tell me that the manager is not available, they have to wait for her to process everything…..it has been for weeks but still I haven’t received any call and refund from them. When we informed that we were going to use this platform to voice put our frustration, they seemed not to care
