Feedback non-existent at Discovery Car Insurance Claims Department

I put a claim for my car in November 2020, Discovery attended to the claim and got my car fixed although the timeframe they took to fix my car is very disappointing. If my kids had not intervened in the matter I doubt I would have received my car back by now. There are still outstanding matters that are not satisfactory and needs to be sorted, including a refund to my daughter as the courtesy car assigned to me was only given for 28 days instead of the 30 days that is stipulated on the contract. It seems Discovery is less bothered to keep the promises they made to me as a client, as I continuously remind them. I have constantly communicated with Discovery requesting that these outstanding matters be attended to, till today they have not been sorted. I have to initiate communication and would receive an email that the relevant department will contact me yet no contact is made to finalize outstanding matters to my claim. I am beginning to wonder if this relevant department exist at all. Discovery does not communicate with me, unless I initiate communication. They treating me as if I am a pro bona client, I am highly dissatisfied with the inhumane service I continue to receive from Discovery and how outstanding matters to my claim still remain unresolved.
