Arrogant Disrespectful Non-existent customer service

<p>I booked a flight with FLYSAFAIR for my father and business partner, I added the travel insurance option to their booking.</p> <p>Their flight was diverted to Durban on it's way to JHB and the arrival time at OR Tambo was delayed by more than 3hours, this is a valid reason to claim from the travel insurance, all I need from FlySafAir is an official letter from the airline confirming the cause and length of delay'.</p> <p>I have 'contacted' them twice via their website, I have called their customer service no. where I was on hold for 24 minutes and 55 seconds on and off with no conclusion reached, I have contacted them on Social Media where I was treated very disrespectfully and still they refuse to give me this simple letter? I only have 30 days within which to lay the claim with insurance and they are refusing to help me, more than 16 days have passed. How do I get this letter? I am not asking much. The flight arrival time was delayed and I need a letter to confirm this....</p>
