Poor handling of Claim

My claim number is ***. My car has been in repairs from 07/03/2015. Discovery delayed to give approval to the Repairer to buy new parts to repair my car and the Repairer couldn't find second hand parts as per Discovery instruction. The Repairer was also delayed to get approval to get additional parts.During that time of these delays the courtesy car had to go back to Avis. I asked Dineo for an extension. Up until now she has not given me a call or emailed me to let me know about the progress of the courtesy car extension. The courtesy car went back on the 24/03/2016 and my life has been standing still because of this Dineo and Discovery Insure. Discovery through its representative Dineo Monguni has taken me for granted and no feedback about the extension of the courtesy car given. I am totally unhappy with this Discovery Insure and don't see myself in the future dealing with this company. Even my partner was introduced to Discovery by myself and I am going to tell her to leave this and even all my friends I am going to tell them to leave this company, even my church members and communities I will tell them to leave Discovery. Please help!!!!
