Poor Service from Discovery Insure

I had an accident on the 31st December 2019 and my car was towed away. I could not get a courtesy car because the staff of discovery had knocked off (problem No 1). My car was due to be assessed on the 6th January 2020 as assessors were only going to be back then. Post the assessment the car was to be towed to Bloemfontein for repairs. I got a courtesy car on the 7th January 2020 which was due to expire on the 6th February 2020 but Discovery extended it to the 13th February 2020 (great). To date, 22 February 2020 the car is still at the panelbeaters and I don't have a car to use and I paid my February subscription to Discovery on the 15th January 2020 for a car I don't have or use. My claim handler, a certain Ushen, never responds or acknowledges emails sent and he is forever not available or on lunch.
