Flights canceled on the start day of our Holiday

This morning after a few weeks of planning we were packed and ready to head to Sydney! 4am wake ups and airport runs.. Get to our check-in counter with confirmation and ticket in hand, the lady shakes her head and asked if we could please go to the ticket office. There the very nice ladies of British Airways took our confirmation and tickets and told us that they have a notice to inform us that Gotogate has canceled our entire booking! After a few hours of being on the phone (Liv, myself and the sweet BA Ladies) The Gotogate Customer Service Supervisor "Ayush Malik" told me to read the T&Cs, no notice was sent to us! Not only was our entire trip canceled hours before take off, our refund of R38000 would take 10 working days to get back to us, meaning we cannot book another flight! Gotogate was the agent linked to Skyscanner that we were automatically re directed to!! Gotogate this is unheard of and unacceptable!!
