Very bad and unprofessional service

I'm on comprehensive plan on discovery insure. Was in an accident early Jan 2018 and send relevant documents except police report (had misplaced the paper with info from police station) on 11/01/18 to Vulindlela Ntsele @discovery who was handling my case. On 12/01 he contacted me requesting details of the third party and I responded informing him that they were attached on mail. On 16/01 he requested the police report of which I later sent on 18/01 and apologized for the two days delay since I was not well and was home after the accident and could only collect the report on 18/01. He acknowledged via email on 18/01.. On 24/01 and 25/01 I made a telephonic inquiry and on both days was told they were waiting for my police info and I informed the person that the info was submitted on 18/01 already. Person promised to get back to me but never did. I then emailed Vulindlela Ntsele on 25/01 to find out where my car was towed to and how far was he with the authorization. He never responded to that mail and got everything on record. I would call and hold for a very long time without any response. I managed to get through on the08/02/18 and spoke to Aubrey who informed me that the claim could not be processed as they were still awaiting the police report. I then informed him that the report was submitted on 18/01./2018 already and that I had been making follow ups and mentioned that to other consultants. He then authorized the claim later that day i.e 18/02/2018 and sent me the confirmation. There was a delay from their side to authorize as they were awaiting documents that I had already submitted on the system and no one was of assistance to me as a client. On 12/02 and 13/02 I was constantly on the phone with them to try and extend the courtesy car hire for me as they delayed with the authorization. They frustrated me as I was told constantly that managers were in the meeting and they would come back to me. On 15/02 /18 in the morning after holding for almost 45min I spoke to Nelly who informed me that the managers were in a meeting, she took my numbers and promised to come back to me but failed. I then called back again in the afternoon and still no one assisted me. I then sent an email to Vulindlela Ntsele who was handling my claim and he still didn't respond. On 15/02/18 I was also on the phone to follow up and never got assistance as I was given same reason that managers were either in meetings or training and no one could assist and all the times they promised to get back to me and as usual no one would call back. I then decided had to pay Avis to rent a car for the extra day as I was stranded and held at their offices. I'm utterly disappointed with the way my problem was handled and to date no one even bothered to follow up on my complaint. The staff and managers couldn't be bothered even after sending endles emails to the manager who chose not to even respond to my complaint. I will not advice anyone to take the Discovery short term
