Discovery Insure poor service

I had an accident with my vehicle,did the SAPS reports and lodged an online claim via the app ( 16 April 2019) which worked wonderful , got the hired car and everything went smoothly until the panel shop indicated they found more damage and my back left door needed to be replaced. I only received my car back on the 10 May 2019. I don't have a problem with the time delay it took but every time i had to follow up with discovery insure as to how far my car repairs was, calling on my phone i was then put on hold while the consultant called the panel shop ( this happened thrice) . Once they discovered it was going to take longer with no completion date known , they would then extend the car hire. What makes me angry is that every time i had to call to get the hired car extended which caused cell phone charges on my side as well as stress to every time call in just to find out the repairs were not completed yet and i needed to get the hired car extended so that i had a car to use. The discovery app with my claim was never kept up to date to provide me with up to date information which is then a waste of an app if it is not being used properly, up till to day no representative from discovery insure has contacted me to find out if the car repairs were satisfactory or if i was happy with the service i received. i have a friend who is with Outsurance who told me for his claim he had a service adviser assigned to his claim and that person provided excellent customer service to him from the start of his claim until it was resolved. Why is discovery not doing this? I have already cancelled my Discovery medical aid due to poor service being experienced with them.
