Fly safair... rather not!!!

Need to change a ticket. Can not get hold of anyone. Not on what's app. Cell face book. I have been on hold 5 different times this more g for over 30 min each time. I have proof of call logs and what's app messages. I cant do it online as it is to cancel a flight. There is jo option on the booking amendments page. It's a co plate joke dealing with them. It's down right disgusting! I will. Ot be booking with the. Again the service is none Exsistant
