Worst service ever ****ers big time

Worst service ever. Booked flight tickets trough them from jhb to capetown and back. 12 hours before flight times were changed without consulting me about times. The times they gave me was to late. I would have arrived there after my meeting. Tried contacting them on their emergency whatapp and email as they don't have a phone number but with no-one answering or coming back to you. Even today no-one have come back to me about it or to talk about refunding.
