STILL WAITING

My flight SA1006, SA Airways, on the 2nd December 2017, from Bloemfontein to Johannesburg was delayed(SA AIRWAYS TO BLAME), thus resulting in me missing my flight from Johannesburg to Margate, on the airline Cem Air. The SA Airways desk informed me that if my flight from Johannesburg to Margate was on a SA Airways airline they could assist in getting another flight to Durban, but because my connecting flight to Margate was on a different airline they could not assist me and I needed to discuss this matter with SAA CUSTOMER CARE. I ended up paying for a flight to Durban and hiring a car to drive back to Margate. Speaking to a consultant at the SAA CUSTOMER CARE DESK is not possible as the voice recording keep repeating that they are experiencing high call volumes. I have tried getting through to no avail since Monday the 4th December 2017. This morning I once again called this number and left the phone on speaker, call started at 8:30, I ended the call at 1:30 YES I LEFT THE PHONE ON ALL THAT TIME. I have also sent emails. Please can you assist or advise?
