No service or care

On 20 June 2018, we booked a flight to East London. The flight to East London was with Safair and the return trip through Travelstart was with Kulula. Unfortunately on 22June I had to see a cardiologist and was advised that I needed to be admitted into hospital to have an angiogram done on 26 June and as such was advised that I would not be able to fly the next day. We have been refunded by Safair. We submitted all documentation to Travelstart and were told there was a 8 week turnaround. We have constantly communicated with Travelstart but have had minimal to no response or acknowledgement. This is now week 12 and are yet to get a response. No customer service at all.
