no customer service from safair

I have tried contacting flysafair since 01 March 2022 using email and wattsapp. It was regarding reallocation of seats and a refund therefore. We booked and paid for a specific seat at the back of the aircraft due to a medical condition after a major op and needing to be near the toilet. Upon boarding we found we had been allocated seats at the centre of the aircraft which resulted in a very embarrasing uncomfortable trip. To date we have received absolutely no help or contact
