SAFAIR / Chubb Insurance policy is worthless

My husband and I were booked on FA229 from George to ORT on 3 March 2024 at 18:35. We received 3 sms's from Safair during the course of the evening that the flight would be delayed as the incoming plane was not able to land, due to inclement weather. At 22:30, we received an SMS that the flight will now depart at 08:30 on 4 March 2024. I went online to change this date/time as we had pre-arranged appointments for the morning of 4 March and could not make this time. I was unable to reschedule and 100% cancellation fee was charged. I paid R2800 for two new tickets (+R1000 for return airport transfers). I contacted Safair for a letter to confirm firstly the delay and secondly the cancellation without compensation as I had taken out a Chubb Insurance policy, offered by Safair when I made the booking. Safair, 3 days later, sent a letter only confirming the cancellation of the flight. I submitted the claim with all evidence to Chubb only to be informed that the insurance policy does not cover flight cancellations (read the small print! why else would you want to take out insurance?). I reverted to Safair to ask for a letter to confirm the delay of 14 hours as this would be covered by Chubb, with a view to at least get some money back. Guess what? Safair refuses to issue this letter. I have written to the call centre all week. Moral of the story? Do not ever think you will get money back from Chubb for a flight cancellation / delay as Safair refuses to issue such a letter despite them having sent 3 sms's confirming the delay and Chubb requires this letter. I will refer this matter to ASATA.
