Worst experience from insurance ever

My car was in an accident last year. Car went ro dals for the assessments was happy. Then i received a call to say my car must come in as in today cause auto ross is closing the following friday. I said i would not be able to as it is short notice and i do have a job as well to maintain. The guy still booked the car but for the next morning as i did not agree to that .i contact ed him to say that would be impossible as i cannot leave my work nor can i be late. So then i was told by the discovery insurer as i complained about the delay she then made a few calls and was at great assistance and told me the date that auto ross will be opening again in the new year as they failed to do so.On the 3rd of January the re opened no calls or confirmation. I then sent him a message as he called me from a cell number . He then said ok bring your car in on the 7th of January All in order.t the 15 of January he calls me at about 1400h to say i must come and collect my car as it is ready. I said i wont be able to as it is short notice.yes but u need to collect your car today still as there is a queue and the vehicle we borrowed u needs to come back fair enough. I said im sorry but it wont happen. The next morning sent my wife to pay the excess and to do the collection. Front indicators not working,park lights not working,bumber was firited on skew,door is fitted skew,paint has that glare when not set properly,bumber grill brand new as well not straight,when driving there's something knocking inside the door,head light covers that was damaged in the accident cracked not replaced and that was damaged by the lady that drove into us.the beading also damaged from the accident not fixed. Why do i have insurance?why am i being sent to backdoor panel beaters ?why am i waiting another week for a response? My car broke down as you coming onto the r300 as the were busy with the radiator and took it out to replace the covers and put it back. There was anti freeze in now theres water in as they replaced it with. Car was not bleed properly were was discovery? O had to pay someone for road side assistance. Why? Discover wants your R460 a month and excess of R7600 as well as so they can skrew u up. Car is standing and i had to hire a car from again someone and not discovery as its not my fault amd and still waiting for the next step. Last but not least i was not given a option of panel beaters as well as referral and no quota or what parts will be replaced and if its the generic or original. So im not leaving it at hello peter. Got all the emails and paper work.
